We use a named socket to communicate. I create an mbuf and use sosend
to send the data. We've been doing that for a while and it seems to
work well, except in this situation.

Unfortunately we're not hiring for a development position rigtht now.
Trust me, we'd love to have an extra coder, especially in the network
arena. But until we ship in Q3 2003, we won't have any openings. If you
are interested in a job at Symantec, you should attend WWDC or Macworld
NY. It hasn't been decided whether we'll attend MW but we're always a
WWDC.

In general new hirees must work at Symantec at least 3 days a week. Our
R&D is done in Santa Monica, CA; our corporate offices are in Cupertino
but we visit Apple more than Symantec in Cupertino :-)
There are 10 kinds of people in the world: those that can understand
binary, and those that can't.
