This documents aims at describing what I plan for Typo to go multiusers

A profile :
	has many right
	
A user :
	has one profile
	has many rights

When a user is created, he's given a profile. His profile is marked as "clean"
The administrator can assign specific rights to that user. His profile is marked as "tainted"
When a profile is modified, changes are made on users who have a "clean" profile.

Here are the profiles and rights :
