As I understand the UDP specification, you can choose if you want to
specify a source port or not. As UDP is stateless, you will often see
UDP clients which do not use a specific source port. (See e.g.
http://en.wikipedia.org/wiki/Udp) sendOSC, AFAIK, works like that and
leaves all receiving up to dumpOSC.
