your reply is too cryptic.

when shim6 is used, one cannot start using another address
without first adding that address to the list of addresses
that the HA/CN need to be aware of (basically add to the
shim6 state).

also, if both home addresses are from the same prefix,
shim6 shouldn't be used. if the home link is multihomed
and the mobile node has multiple home addresses from the
different prefixes, then shim6 is applicable.

ofcourse, one can do all this with shim6, but then quoting
you "shim6 is trying to solve world hunger". ;) (hope you
don't mind it).
