I assume this dbus api discussion is becuase of the new dbus api created to allow, among others, mycontacts to start a gv call using qgvdial. Once I suggested epage and uvatbc this I would like to give my 2ct:

Telepathy is great and the more I work with it the more I like the idea. epage's TOR has given us telepathy support for gv. I remember reading somewhere epage explaining the difference between his two gv implementations and why having a dialer had its benefits in some scenarios. I think the standalone dialer and the "connected" telepathy implementations serve different scenarios and/or wishes.

The non-telepathy api only makes sense if it is really simple and right now it is - just a call with one argument. Anything more than that and I think uvatbc should just create another telepathy implementation just for the sake of it (just kidding) - there is no point on trying to create another framework.

I can't imagine why this particular api would ever have to change but if does we will have to deal with it.

Another reason why I suggested the api is because the dialer needs to allow the user to select a contact from the phone's contact database and instead of having uvatbc create another contact browser he could just use mycontacts to select the contact.
