[gameprogrammer] Re: recommended size of data for udp packets

If I understand it correctly, a packet that is larger
than the client's MTU would be broken up and it's the
responsibility of the server to put it back together. 
This is where the packet header comes in.  We'd know
how much data to expect so we just recv() until we get
it all.
If that's not right I'd be very interested in hearing
the solution.
