I don't know of any system to do this either, but I think it is theoretically possible.
If you can get your NIC to listen to *any* destination MAC address (promiscuous mode), why would it be
impossible to let it listen to two different destination MAC addresses.
But this remains theory. I don't know of any card that can do this...

I think such a feature might be useful if you want to do 802.1q vlan trunking,
but I'm not sure about it. The applications of such a feature will be rare anyway...
