By setting the socket options SO_REUSEADDR and

if the two instances of the process are running as
different user ids, the bind attempt by the second
instance of the process fails with "address already in
use". Does anyone know if there is way to get two
instances of the same process running as different
user ids to reuse the same UDP port on Mac OS X?
This is a very odd thing to want to have happen. What behaviour
would you expect from such a shared port with regards to inbound
traffic?
