You probably know this already but it is possible to operate UDP in 
connectionless or connection-oriented mode. Connection-oriented is 
somewhere between TCP and connectionless. In connection-oriented mode I 
suppose you would want to know if the other side is there or not, 
whereas with connectionless you probably just want to fire and forget. 
Not sure if this affects what you are doing but might help explain what 
you're seeing.

Cheers,

Chris.
