Is it possible to have multiple instant of AC on the same server using the same source?

The core code could be placed in a single location and linked to using symbolic link. Configuration files will be local to each instant. Mediawiki has something like this and it is useful for multiple install and maintenance.

Sorry, just posted this in the other thread on the subject, so i'll just point out where i've got to:

I'm currently running 2 users on 2 different browsers (FF and IE6) - same set of files, different database tables being used for each user, with a custom config file being used to call the right set ot tables according to the login details.
