This is the same situation than telepathy-sofiasip. Thanks for bringing
this, I did not cover that case.

I'm wondering if the CM should implement the ContactList interfaces
anyway, but keep the roster information locally in a file instead of
relying on server storage. For this, it could use the offline storage I
describe in my point 6. So all API like adding/removing contacts,
setting an alias, etc will just work like any other protocol.
