Heh... I'd noticed that when looking at the Linux implementation,
but I wasn't awake enough to try actually creating one on BeOS!
I did so (just copying the Linux one) and I no longer get 'unknown
protocol'.  I now see:
 "sendto: Address family not supported by protocol family"
but I guess I'm getting closer!

Looking at the code source I have (the original BSD, I think), it's
beginning to come clearer how it's doing things.  [As you can tell,
I'm not very familiar with net access code!]  The socket call just
gets the 'family' parameter from the protocol structure it got from
getprotobyname, so I guess the BeOS one does just what you show above.

Thanks for the tips!
