Yeah, telepathy is all fine and dandy, I've seen the presentation, but currently cannot be interfaced - maybe it's coming.

Second, dbus ain't the wrong way, it's low level, that's exactly what's needed.

For instance I wanna program an interface from GNU Emacs, so you can dial and send SMSes from BBDB etc. Dialing is already working, now the SMS is the part that's missing.

For this, I'd think a low-level way would be better, then interfacing to telepathy... But I wouldn't be opposed even to telepathy, if one would know how to do it now.
