Thanks. I'm getting a better picture now. Thanks for elaborating so well. Please note, that I think in Post#2 your directory structure is different, hence my seeking clarification on the structure. Your 'home' folder is not inside 'modules'.
I had not even considered nesting the modules folder, where you've shown it being a child folder. Interesting. Not sure when it would ever come to practice, but good to know.
What is the difference between modules::load and modules::run? A cursory look at the code looks like run also loads the module passed.
With reference to the line below, do you check if data['current_action'] isset in your index method of the controller then?
Code: $this->data['current_action']=$method; //used inside my modules
This next part is probably application specific, nonetheless, anything interesting to note with the following snippet?
Code: $content = ($module=='admin')?modules::run($module, $this->data, $method):modules::run($module, $this->data, 'index');
}
else
{
redirect('');
}
I didn't quite follow you when you say you use a custom library to load all the options inside the data array upon initialization and then just array_merge. I'm a bit rusty on CI (took a sabatical for a few months learning javascript), but I thought when libraries were loaded, CI automatically checked for a similarly named config file. Seems like there would be a way befitting of the "CI way" to have the modules check for a config file and to load that. So when a module is loaded, go ahead and load the config array associated with it. Not sure if that would connect to the module, or maybe one of the views.

I apologize for not explaining everything from the beginning. This is what I have done in one of my configuration tests with ME & smarty Template System. I will start with the autoload file, your routes.php file will stay as above. Ofcourse you can do some trickiness it there to load another controller(I don't see a need for this due to modules) When you use ME it this configuration everythign becomes a module that is loaded from the url. I check my method or current_action inside my module and the only thing on top is the error flash messages or contact(email send function),etc.which is mapped from the index function via function_exists. Please try to follow along as I give you some files for example.
autoload.php
Code: $autoload['libraries'] = array('database','session','validation','smarty_parser','environ');
$autoload['helper'] = array('url','file','form','modules');
$autoload['language'] = array('site'); //app/languages/english/site_lang.php
make sure to add smarty libs to your app/libraries/smarty/ directory, create a app/libraries/smarty_parser.php file and app/config/smarty_parser.php(follow 1st post link) In the research that I have conducted I have found that all you need is a default_layout.php that contains this code
Code: <?=$template;?>
and teh rest is up to smarty and my special site environment variable library. I will show a basic configuration of this and my lib to hold your environment configuration.
inside my smarty I have added these to setting to control my template delimiters (this way anything smarty will show as an html comment and you can tell you designer not to touch the comments but work around them, plus it looks easier on the eyes 
Code: $config['left_delimiter'] = '<!--{';
$config['right_delimiter'] = '}-->';
okay, this is where the fun begins, yay, fun.
create a environ.php inside app/config/ this will hold your template configuration
Code: //templates folder name in filesystem
$config['templates_folder']='templates/';
//current active template name
$config['template_name']="CLIENT_1";
//template config file name located inside template_name/config/ directory
$config['theme_config_file']='theme';
I will continue with app/libraries/environ.php in next post, I thank you for being patient. I'm sure you will be pleased with it.

this is where the configuration of modules and such begins. everything above this is environ lib.
this is how I have my file system structure setup for one template:

tpl_head.php
tpl_foot.php
tpl_left.php
tpl_content.php
tpl_index.php //this loads your head foot left right and any other templates
CLIENT_2/
/* RECURSION */
configure the main smarty template which loads all the rest of the templates from variables
this is what your tpl_index.php should looks like
Code: <!--{if !empty($head_tpl)}-->

on top of all this great commosion you can create your own custom smarty functions inside app/libraries/smarty/plugins/
oooooohhh, pluuuuuuugiiiiiinnnns. very nice touch.
app/libraries/smarty/plugins/function.site_url.php
Code: <?php
function smarty_function_site_url($params,&$smarty)
{
//check if the needed function exists
//otherwise try to load it
if (!function_exists('site_url')) {
//return error message in case we can't get CI instance
if (!function_exists('get_instance')) return "Can't get CI instance";
$CI= &get;_instance();
$CI->load->helper('url');
}
if (!isset($params['url'])) return base_url();
else return site_url($params['url']);
}
?>

I would appreciate any comments at all and whatsoever a nice job would be nice too. Anyway, I hope that someone takes this lib very seriously as it has a lot of power due to the fact that it uses ModularExtensions and Smarty combined. Any and all input is welcome as always.

and this is a module for ya as well.
home.php located inside app/modules/home/controllers/home.php
Code: function index($_data)
{
if($_data['current_action']=='contact' && method_exists($this,'contact'))
{
$this->contact($_data);
}
//$this->sibling_content=($this->sibling!='')?modules::run(get_class($this).'/'.$this->sibling.'/'.$this->sibling,$_data,$this->sibling_method):'';
$data = array(
'current_page'=>$_data['current_page'],
'current_action'=>$_data['current_action'],
'title'=>get_class($this).' - '.$this->config->item('site_name'),
'page_title'=>'Tulsa / Broken Arrow - Oklahoma Interior Design, Renovation Services | Elegant Accents '
);
$data=array_merge($data,$_data);
return $this->render('ci:'.$this->environ->template.'tpl_index',$data);
}
as you can see I'm not loading a mass load of modules yet my pages have so much data on them and all that good stuff
Do you Google much?
I Google much alot.
