I found two ways to work with different applications in CI.

A)
You can use the configuration recomended in the tutorial and get like some this:
http://ellislab.com/codeigniter/user-gui..._apps.html

/system
-/apps
--/app1
--/app2
--/appN
/app1.php
/app2.php
/appN.php

Advantages

* Clearly apps separated
* Easy to move/copy apps


Disadvantages

* Duplicate code
* One config for each app
* Is not friendly url

B)
Or, if you are working in the same configuration, maybe you wan't modify each configuration file or create one loader for each app. So you can use controllers directory to separate your apps:

/system
/application
-/controllers
--/app1
--/app2
--/appN
/views
-/app1
--/controller1..N.php
---/view1..N.php
/Models
-/app1
--/controller1..N
---/model1..N.php
-/app2
-/appN
/index.php

Advantages

* Only one config file
* Fast navigation in file system
* Use Don't repeat yourself

Disadvantages

* Possibles collitions for personalized CI elements (MY_helper, MY_library)
* Path to call views long ($this->load->view('app1/controller1/view1')
