Someplace I've a sun doc that discusses how to do this on SunOS and
Solaris. The reason you might want to do it might include redundancy
(I've had NIC's die on me, sometimes from overheat) and possibly
increasing bandwidth. In fact, for the second reason, it's relatively
commonly done with PPP links, which amounts to two NIC's on the same
network. 

I'll keep looking for that doc, and upload whatever suggestions I can.
