- As long as you are using two different interface cards you can run two IP
- stacks concurrently no matter what drivers you use.

- Sorry, but I disagree on this. If you have two cards and each card
- has its own stack, that should work. However, if each stack wants to
- talk to each card, you are back with the problem that PKTMUX (or
- whatever it's called) usually solves and isn't being taken into
- account here plus the need for a multi-homed host. Most PC TCP/IP
- stacks are not multi-homed (other than routing, think of one good and
- implemented reason for having two cards under one stack), so that
- precludes this from working from the other side. In short, with
- appropriate shims and simplifying assumptions, you could probably get
- this to work. But, out of the box, no way.
