Most Unix networking has been on routing, not bridging.  I think I know
what would be needed to do real bridging, but I don't think you would
gain anything with the IP filtering code in there, without making it
far more generic and putting the accept or deny hook at a much, much
lower level.

I _could_ imagine a BPF-based bridge, which might be what that drawbridge
thing really is; I've not looked at it.
