How much performance gain do you expect?
I mean is it worth using UDP in opposition to TCP?

I've no idea how much the latency should decrease by just using UDP
instead of TCP.

I'm not quite sure, but shouldn't it be possible to just replace the
TCP-specific part in the SOCKET implementation by some UDP related code?
