Hi,
can I use dial to set up an point-to-point udp connection
and force the local port to a known number? I guess
that if the answer is no then I must just do a connect()
and use the 'headers' option and explicitly set the headers
in every packet - no great hardship, more a question of
does the plan9 network syntax support such a thing?

The local port is the second argument to dial:
fd = dial("udp!135.104.9.1!31", "21", 0, 0);
to send mail from port 21 to port 31.

Man I got mail on the brain. I meant to send udp from port 21 to port 31.
