Layer 2 (stealth) firewalls - PBR?

If I can interrupt the usual questions for some product requirements discovery.... Over in the networking community on OpenSolaris.org, a couple of us are pondering the question of what it means to do policy based routing (PBR) at the ethernet (MAC) layer. For IP, the use case is well understood and people everywhere do it with firewall software, if only to make up for the inadequacies of their routing tables however when it comes to ethernet, we're kind of scratching our heads....so, some questions.... Does running a stealth (bridging) firewall remove the need for PBR? Do people still do strange, quirky, things to packets even when they don't want them to go through IP? If you're using bridging to support your firewall (that still filters packets using IP header information), can you shed some light on why/when you want to send packets out a specific NIC regardless of what the forwarding table for the bridge says?
