It should work, but you don't treat the case of groups having this  
local role, e.g 'group:some_group': ['Owner', 'MyRoleGuest'] in the  
dict.

The use of groups in various local roles assignments is encouraged in  
the general case  because it's usually less prone to modifications  
(which can be costly, especially for folder hierarchies).

That's almost impossible - and breaks things like tab navigation,  
which CPS supports very well (a strong point for ease of use compared  
to most apps heavily based on session persistence)

We don't have that currently, either.

Can't say, I'm french, too :-)
