Running Multiple Applications with one Codeigniter Installation - Dirctory Structure

[eluser]noCodeMonkeys[/eluser]
Hi All,

Any help on this will be appreciated. I have read the user guide topic on this subject and am trying to create a directory structure as follows.

webroot/codeigniter/system
webroot/joes_bar/applications
webroot/wendys_wicked_ways/applications
webroot/freds_funny_fans/applications
..and so on.

Each user is in their own folder w the CI/applications folder copied into it. I want them to all use the same CI/system dir. I understand that this is not how the user guide says to do it, but I want to know if it's possible.

I have it set up to the point that a simple page will display, but as soon as methods are called that are stored in the system/dir all the paths point to codeigniter/applications not to webroot/joes_bar/applications (for example).

Is it possible to set it up the way I have noted?
