We've got a day of talks at OpenStack Boston.  The schedule isn't posted
yet but here's some information:

OVS supports VxLAN as a tunnel encapsulation, but doesn't natively support the 
control path.  I don't think it would be that difficult to write flows that 
implement the control path in OVS, though.
