You can almost do this today using Crossbow VNICs.  The VNICs are
still associated with an underlying physical NIC but traffic between
them is looped around in the VNIC code.  A different physical NIC
(which doesn't even need to be connected to a network) would be used
for each of the "virtual switches".

We've talked about improving this so that the VNICs are instead
associated with a virtual switch.  It seems this might be as simple as
creating a "null" GLDv3 driver to act as an anchor point (presuming
that we include the ability to create new instances of the null
driver).  I don't think that anyone did this work yet, but could be
wrong.  Nicolas?
