Keep in mind that large transfers (maps, voices etc.) would
get transfered a lot faster with TCP unless you roll your
own windowing...  The initial transfers and setup may also
benefit from the much better checksum functions used by
TCP compared to UDP.  One problem could be firewalls, though.
Some block just about every incomming TCP, others don't
particularly like UDP...
