Martin,
Here's the patch.

Hi Fredrik,
I've started to make a patch to be able to bind to a local ip address
when using zmq_connect / zmq_bind. I need this since I have a bunch of
ip addresses on the machines that I will use 0mq on.
It's only a few lines in tcp_connecter.cpp to be able to do this. Have
tested locally and verified with $netstat -tn to see that i actually
works. (The hole patchfile is only 31 lines).
Nice!
However, I don't have the knowledge for make the changes that's needed
to the api to add an additionally parameter for the functions
zmq_connect and zmq_bind.
What about using PGM-like format for the address:
zmq_connect (s, "tcp://eth0;192.168.0.111:5555");
