I've now eliminated the unnecessary listen sockets.

I've tried deferering the creation of the broadcast socket until it's 
needed, and i can't get it to work. Odd, because I'm using the same code, 
just called at a different place.

I've tried running it on a different computer from the server and I can 
see packets going through the switch, but the server doesn't record 
anything as received.

The sender is saying the port and socket are the same as in the working 
version, so I don't quite know what to look for next.

I guess my next step will be Wiresalmon and see what the packets actually 
contain.
