In the meantime, consider trying udp2raw[1], which will allow you to fake UDP over TCP (by colluding on both sides of the tunnel) and works pretty well on coffee shop WiFi in my experience.

See also udptunnel, an older implementation of the same idea - http://www.cs.columbia.edu/~lennox/udptunnel/

The idea is pretty different. This one is implemented by a regular tcp socket, udp2raw is implemented by raw socket. Raw socket based implementation bypasses congestion control/retransmission/head-of-line-blocking, thus has much better theoretical performance.

Oh, really? Interesting, I had thought that udptunnel did as you suggest. Perhaps I was confusing it with something else.
