IÂ´ve made the integration for e107 of Collabtive 0.4.6.
IÂ´ve made the clean theme, the plugin install, and wraps for user tables, db connections, and a couple of improvements.

Please create a user class named 'collab_admin' and assign the users that you want to be admins in collab.
Create a class named 'collab_users' and assign all the members that are meant to use Collab.
Create a class named 'collab_headadmin' and assign the main admin to that class
If you need to adjust the database prefix just that in file config.php
