Which one?  Every machine I use has at least two, not counting loopback.
Not to mention the fact that some of these addresses change, no control of
my own.  The powers that be decide that everyone is going to use their
phone extension as the host address, where before everyone was broken down
by department.

Not saying not to do it, but there's quite a few things you need to keep
in mind.  If you use the IP address of my ethernet card, congrats, you
just bound to a 192.168 address, and anyone that has $20 for a cheap
ethernet card, or a spare tun device if your program isn't careful, can
pirate the software.  If you force me to use real IP addresses, I can't
use it at all at work, where I'm behind a firewall, with only 192.168
addresses.  For that matter, I've had my ppp address change on me with
little notice.
