Hi Kyle,

I'm curious if you can share your long term plan for LISP.  In
particular there are three areas that I was wondering about:
 * L3 support.  Obviously OVS is very Ethernet centric at this point,
resulting in the need to play games with MAC addresses.
 * Additional LISP data plane support.  LISP encodes more control
information in the protocol itself compared to the existing OVS tunnel
implementations, which basically only have the tunnel ID.  It looks
like this implementation generates nonces on transmit but otherwise
doesn't try to handle the other pieces.
 * LISP control plane components.

What do you guys see as the ideal end result?
