bridge and features on virtual bridges

hey list, hi theo

we are develop on an firewall solution.
now we have an idea for the brodge interface:

we would create the bridge as an more user system. let me explain:
when a customer use an openbsd bridge for other customers (A,B,C) is this not a problem, all custumers from him can use the same Internet interface, right?
When now the operator will give to customer C another net from ripe, can he use the same bridge at this moment? At the moment not, an brigde isnt an router.
okay, this I know, but has anybody at the moment an idea for create this feature? The fw1 cant this ;)
We discuss at the moment an mac-nat, is this possible?

thank you and a nice day
