Well, as it's missing for POSIX 1003.1 compliance, I guess supporting it will be
great. Not mandatory for R1, thought, but it's not like it's that hard to
implement.

I saw this, yes.

Sounds good to me, indeed.
BTW, these sockets are supposed to be unbounded.

Then just implement a noop socketpair() in socket.c (both in libsocket and in
libnet variant) and I'll self assign the task to implement it later.

I don't consider this as urgent as reaching beta stage of OpenGL Kit and the
network stack missing features: DHCP, 802.11 support.
Maybe that's because I never used socketpair() so far ;-)
