Can you give us an idea (or point me to a README or something) of what
features it has specifically?

Is it independent of something like usocket? I'm just wondering what impact
this has on portability. Usocket as it is has enough trouble with
portability; I've had plenty of trouble making everything work as intended
on all OS/compiler combinations. I can see the advantage of going for CFFI
and doing the bindings yourself, but the cost is more testing required to
verify that everything works.

I have a publicly accessible repository at

Thanks for sharing. Not sure if I'll use it, but I'll definitely keep an eye
out. :-)

Liking the look of blackthorn. :)
