Ahh great, now I'm blind! :)
Seriously - it seems to confirm that I was confused. Looks like you can
either:
a) dup the socket to stdin/out, then exec a program (a la inetd); or
b) keep stdin/out and the socket, and multiplex between them (telnet).
Since I want my program to act as a pipe source/sink, rather than
exec-ing something else, I'll have to go with b), which means I'll have
to face the select(2) music.
Anyway, thanks for the pointer...
