The problem with the EL (afaik) is that it can't call a method, such that evaluating "isUserInRole()" will not work, nor will Set.contains(), even if we could get the appropriate objects in scope.  

We would need to ensure that EL has access to a complete listing of the user's roles in the form of a Map with [roleName:true] as entries.  Then the EL {userRoles["admin"]} would return 'true' if the user is in the 'admin' role and would return null if not.

This is mighty ugly (but it would work).  Though we still would need to figure out a way to produce the roles map and make it available.  I'm just brainstorming--does anyone have a clearer idea?

Sounds like an option.
