Scott has started on something, but has not yet committed.
We welcome your new ideas!

When you say separate security from profile management, I didn't 
realize they were coupled in J1

Sounds a lot like J1 Groups, with two additions: hierarchies, custom

Have you any experience with writing either a Jetspeed Security service 
or a Jetspeed Profiler?
Are you familiar with the J1 profiler and security service code?

Have you looked at the Java (TM) Portlet Specification?

Thats new to me. I really like the concept and it seems like an 
important feature for a portal.

I like the idea of extending the profiler.
I never thought we'd get so much mileage out of the first one.

Remember that the portlet spec now defines a clean separation between 
the portlet application (your portlets) and the portal (Jetspeed).
What you have proposed seems to fall under the portal category.
