Telepathy knows this because you have a Channel open to that person,
which stores this state, and any entity caps you were given during that
session, etc.

We've not come across anything that needs it as yet; that's why Gabble
doesn't export it currently. As Xavier spotted, we could put multiple
presences in for one person, and then say which resource they belonged
to, which has the problem of requiring all clients to understand
multiple-presence/resource contacts to use XMPP, or maybe just have a
list of the available resources as a parameter to the main presence. I
won't dismiss it out of hand, but it seems very unimportant to me
provided Gabble's choice of resource for outgoing events is correct.
