In the case where HA are placed in geographically separate locations,
this is indeed a multihoming configuration as defined in
draft-montavont-mobileip-multihoming-pb-statement (for host mobility)
and draft-ietf-nemo-multihoming-issues (for network mobility). 

As such, and since it covers for MIP6 and NEMO,  I think it falls into
the scope of the Monami6 BOF (http://www.nautilus6.org/ietf). However,
we have not yet initiated the discussion on this topic on the Monami6 ML
and it may be too much discussion for the BOF. If Monami6 can
become a WG, I think it should be added in our charter as a Monami6 WG
item.

Thierry
