Has anyone tackled writing a user administration module in Silverlight 4?

Just wondering if there is anything available that makes it less of a PITA than rolling my own from scratch.

Need to be able to list, edit, add, and delete users, roles, and users in roles. Need to be able to edit user profiles as well.

Seems easy if you are just worried about editing your own user information.

All bets are off if you are managing other users.

I can do this by going after the aspnet tables directly (or via services), but it's a pain in the a$$. Profiles are a bigger PITA.
