Ah.

| Why are you limited with bridging between only 2 interfaces?

Well, it only listens on one interface, and packs up the packets in IP
and sends them off in UDP through normal networking means.  And listens
for UDP (IPADDR_ANY) and unpacks and puts them out on the interface.

What I'm currently using is "SIB", btw.  (It's on freshmeat somewhere if
you want to look.)
