Python, but not platform dependent :-)
It would be nice to provide a shim module to provide stuff like this in
a way that any platofrm could use. But when you look at the trouble it
took to find a reasonable way for Ka Ping's guid function to locate an
Ethernet address you'll agree that it would be a lot of work.
So probably reading /proc/net/route is a good bet for a limited range of
platforms. OpenBSD is another place you won't find /proc/net/route.
