stable, but way too low-level to be used directly, it needs wrapping.

It comes with a wrapping, but its way too high-level, and has been
abandoned as having taken a few wrong turns. Vortex is better if you
want a multi-threaded library for C/C++.

Beep performance can be much poorer. Its essential to use window sizes
in the close too 100K range for bulk transfer, and to make sure you
fill the window with data, probably pre-sending 5-10 messages of about
10K each, to come close to TCP. And disable NAGLE :-)

I'm sure BEEP can do much better, there is no reason in the protocol
to be slow, its all in how you use it. I hope! I'll write up
recomendations when I have them. Still doing testing.
