I'd put this unifying job in the lap of Galago and something a little on
top of it. Galago is the component which is meant to read your address
book and see that these contacts on different protocols are the same
person. The telepathy-feed could put in a lot more of the info from
Telepathy (capabilities, handles, existing channels, etc) so that when
the other bit (the widgets, I guess) are trying to implement a policy
like; prefer Jabber to MSN; prefer online people to dead people; etc, it
can make the decision with information at hand.

MC is meant to be a daemon, rather than a UI component. Yes, we should
make sure that these widgets are provided, but it's orthogonal to MC.
Probably just libgalago-gtk, or libtelepathy-gtk or somesuch, which will
make EDS, Galago, MC or CM calls to decide/do what the user wants.
