I guess you are talking about MIPv6 here, right?
If not, stop reading.
If yes, i think that in order tu use the mipv6 protocol in a multi-homed
scenario, there is no need of a home agent.
I mean, a host within the multi-homed site has multiple prefixes, and
suppose that all of them can be used to initiate a communication. So
dependin on a number of considerations (policing, availability, which
prefix is selected by the other end, etc) one of those prefixes (PrefA)
is selected to be used in a certain communication.
T that moment, PrefA::Host becomes the Home address and all the other
addresses available becomes potential Care-off addresses. Whene there is
a failure, the host send a BU to move the communication from the HoA to
one of the other CoA available.
So no need of HA (or if you want, the mobile node is also the HA)
