I'd be interested in something like this. Maybe something along the lines of:
brctl addtap <bridge> <device> # only allow 1 tap? i'd guess so, but if not
brctl deltap <bridge> # then add a <device> param to deltap
This would be very useful for me, as it would make hooking up snort
to a linux bridge very nice and easy.
