I'd like to have a UDP instance too. As I've mentioned, in theory, running a VPN over UDP should work better than running it over TCP. When you have TCP layered over TCP, if you run into network latency, you can have both layers retransmitting, and the upper layer can exacerbate the latency of the lower layer with the extra traffic.
Note: On my Pi, UDP performs MUCH worse than TCP. I haven't figured out why.
