The draft is quite readable:

(AFAIK) Not at all.  They try to solve similar problems (or at least there 
is some intersection).

A word about the implementation.  The interception mechanism for LISP 
tunneled packets in ip_input/forward is *horrible*!  Some of that is due 
to the design, but I believe it can be implemented much cleaner if you 
were to use the pfil(9) API.  I'd really like to avoid putting this kind 
of stuff into the main ip code as it hurts readability a lot.
