Yes, a bridge is not routing. but how do you route between two interfaces on
the same subnet? AFAIK you can't, hence requiring a bridge.

Yes, bridging allows everything through as if the device were simply a piece
of wire.
There are some apps that will allow you to filter this traffic and set up
rules.

I used http://ebtables.sourceforge.net/  ebtables to do this and it worked
like a bomb.

Similar chain string setup as iptables, this made it fairly simple to pick
up and run.
