All you need do is write the object to a byte array. See
http://mindprod.com/fileio.html for how. Then you can bundle that
byte array as your payload in a UDP or Multicast UDP packet. The only
catch is just how long can the packet be? I don't know off the top of
my head how big a UDP packet can be, but I would think it would be in
the order of 128 bytes or so, unless there is some sort of packet
reassembly protocol for jumbo packets now functioning.
