You might also check with Jay Kint (jkint@invisible.net) about the Python
work he has been doing. It might make sense for you guys to put your heads

The PyBXXP (Python implementation) is open source and is available at
If you are a python person, I would appreciate any help you can give.

It would seem to me that a bxxp well-known port number should be defined,
there is a requirement be  passed "up" to all applications on top of beep
a port must be part of the URL for the bxxp peer. I don't think requiring
a port number is a good thing.  

Since (as I understand it), specific channel numbers are *not* assigned to 
specific applications (unlike port numbers), that the only thing an
would need to specify is an endpoint for a bxxp peer (endpoint being ip
and port).  But this is part of the TCP Mapping, I'm guessing, which I
looked at in detail very recently.

To restate:
In the modal case, an app that works on top of BXXP only requires a IP
(in the TCP Mapping) to specify a peer. Authentication and TLS may have
naming requirements for specifying the peer endpoint.

Is this right?
