  I'm presuming that they're part of the solution.  If so, what *else*
is required?

  I'd like a clear problem statement.

  From what I've seen of your requirements, you want the ability to have
multiple "groups".  What you call communities of interest.

  i.e. a realm is tied to a specific home AAA server.  But that realm
can exist in different contexts, and have different routing properties.

  e.g. foo.edu belongs to eduraom, but ALSO has a commercial agreement
with a roaming provider.  It wants to inject different routes into those
two different routing fabrics.

  If that's true, then the first points you raised are only steps 1 and
2 of the solution.  Step 3 would be to have a registrar which would
coordinate group membership.

  I think the confusion for me is that I don't see why additional
complexity is needed.  Roaming operators already do roaming by realm, in
a particular context.  e.g.  "example.com gets routed through the
wireless broadband alliance"

  For me, it looks like step (3) is widely deployed.  That's why I'm
interested in talkiing about steps (1) and (2).
