Debo:

A tap is nothing different than a VM vnics from a switch perspective, it still contains a portion owned by Nova (the tap itself) and it connects to a port, which is owned by Quantum. So in essence, the tap still has both a "vif" and a "port" in this terminology.

Thanks,
Kyle

I propose that basic read access of “cap” off of our major objects: network, port, interface be included in our first release.
