Multiple projects with the same application folder.

Greetings, guys...

I've this situation:

I'm creating a system where will run multiple projects using the same application folder. Something like this:


project1 ==> newApplicationFolder

project2 ==> newApplicationFolder

(...)
projectN ==> newApplicationFolder


I need use this way, cause the projectN folders will have just the index and some configurations, like the sqlite database. And, that is the point: the projects folders will be named by the user, so, i've not a static folder to indicate in the database.php. Any idea to how I could to do?

It's possible extends the config file, or create a personalized config file inside the projectN folder?

Thanks, guys.
