While it's true that the ground level users are in an aloha network it 
isn't true that the high site repeaters are. They are truly in a CSMA 
network. I think what Pete was getting at is that we need to be building 
those high site cross-channel digipeaters so that they check for busy 
before they transfer the packets from the alternate network to the main 
144.39 network.

Pete - Is that where you were going?

I know it was the question I asked the other day, but haven't seen an 
answer to yet.

Can we see some recommendations and real world experience on how to route 
between the networks responsibly? For instance: In Annapolis how are you 
routing the packets?

Note: For this use it would be really, really nice if we had a dual 1200bps 
port TNC that understood WideN/TraceN routing between the ports. (Of 
course, it would be really nice if we had a 1200/9600 ported TNC that did 
that too. A KPC9612+ can happily route between the two ports, but it can't 
do WideN on that.)
