As far as I'm concerned, the way forward is to scrap BIP 10 and build up
something new that is flexible and extensible. Also, my understanding
is that there may be room in the payment protocol for this stuff though
I'm not sure if it is really adapted well to all the steps: exchanging
public keys, creating multi-sig/P2SH addresses, proposing multi-sig
spends, bundling meta-data needed for lite/offline nodes, aggregating
signatures, and any other details.
When I start multisig integration into Armory (very soon!) I'll write a
list of requirements for the new format/process and post it here for a
wider discussion. Certainly, if the payment protocol can already handle
all this, that would be awesome.
