Fully agreed!

+1 ;-) One of my own outstanding requirements I haven't found time yet to
find a solution for.
We've been here before and several solutions have been suggested in the
past (including one of my own). Lets try to get this right once and for
all!

I am bringing this up as I have been privellage to quite a few vendor portal demos lately allowing me to see both the good and the bad of multiple implementations.

> I think the first profiling/navgation implementation would be assigning n number of roles to a top-level folder.  Then allow the Profiler to aggregate what Folders a user has access to by comparing the roles that user is assigned to the ones required the Folders required roles (ACL?)  I think this approach is already somewhat in place but it just needs some final implementation details.
