Hi all!  Does anyone know how #receiveUDPDataInto: decides which
network interface to read from?

I want to read UDP data only from a particular interface, the only
reference to this subject I could find:

  http://lists.squeakfoundation.org/pipermail/squeak-dev/2003-September/065912.html

seems to indicate to send #primSocket:connectTo:port: to the reading
socket as a unorthodox way to force-set a particular interface..?
Will this work or is there a better way?

Thanks,
  Chris
