Generally, I agree. I think using shims for multihoming generally seems
to me to be an engineering problem, while trying to apply them for
mobility seems to veer off into research territory.  I talked to many
people in the hallways about the interrelation between multihoming and
mobility; this sounds like fodder for a bof in Paris / Vancouver.  

I'd strongly suggest that we focus on getting the shim work going forward
for multihoming and revisit the relationship between multihoming & mobility
seperately.  We (the IETF) are much better focusing on a single problem
space.
