IMHO I see no reason to focus only on client-based or network-based solutions. FWIW the DMM solution space:

o is incremental to an existing IETF mobility protocol, be that client-,
  network- or even transport-based.
o or alternatively may not depend on a specific mobility protocol at all
  i.e. non-anchored solution is also in scope.
o solution is backward compatible in a sense that if a host or a network
  does not support DMM, nothing breaks.
o focuses on IPv6 because anything IPv4 is just NAT-games.
