Right, if you place the code in dbus-launch it can just give you back
what CK knows or fallback to X storage instead of launching a new
process.

No, I already agreed with Havoc that this wouldn't have any extra
benefit and would be a pain to maintain. Given that CK knows which
session goes where, it would be possible to talk to other session
buses of the same user anyway, a simple GiveMeMyOtherBuses() DBUS
method would be enough.
