Actually, I'm interested in having servers that can
handle thousands of connections, which in theory could
happen if ISPs start caching torrents. TCP has a bit
more overhead per connection, and some socket

UDP could do it with just one open socket. Also, we
have built-in error correction in BT, so it may be
more efficient to drop the overhead of TPC's checking.
I think these are the concerns that led to UDP based
tracker implementations, but I'm not sure.
