You might look at what we currently do.
1.  Using UDP, you can broadcast a packet to every machine on the LAN.
 That's what the client does now.  The server detects this and sends
back a UDP packet telling the ip and port where the client can connect
over TCP.
2.  Use TCP for the actual game connection.  Our data is not
redundant, and there is no performance consideration here to suggest
using UDP instead.

HTH,
