[interfacekit] Fwd: Preliminary registrar info

Folks,

DarkWyrm and I are going to be working with Tyler Dauwalder and Ingo 
Weinhold from the Storage Kit on the nefarious registrar.  We'll be 
hosting the discussion of the joint venture here.

Good idea.  Can you take on documenting all this information?  I think 
we should also document what the registrar's responsibilities are -- I 
don't think there is a single place where all this is listed together.  
I can do this if nobody else wants to.

It seems to me that the easiest way for this to happen is if 
BApplication checks to see if it is the roster and names its port 
accordingly.  In fact, this is probably the *only* way to do it, since 
the port_id is private (to BLooper, which BApplication is a friend of) 
and you can't rename a port after it's been created.
