No, but this could be easily added.  Also, no spanning tree.

I can only speak for Drawbridge.  Never really put ipfw or BPF through
a stress test.

We are in the process of trying to measure its performance.  Lack of
any good test equipment is making it kind of hard to get good numbers.
A interesting preliminary number was 80Mbs sustained of 64 byte
packets.  No filtering rules involved.  On more realistic traffic it
looks like it can keep a 100Mb wire saturated with filter rules.

Hardware was a Pentium II 300, Intel 100B PCI card.

> * do you support only two network cards, or more of them ?

Same as above.
