If we put stuff in hal, this will (other than the carrier-specific 
stuff) just be a matter of calling a couple of device methods. Does that 
seem reasonable?

I'm not convinced that's a good idea. Discovery seems to take a 
significant quantity of power, and I was under the vague impression that 
it interfered with existing connections. If you know the mac address of 
the device in question, why not just l2ping for it rather than 
performing full discovery?

As I mentioned, I'm considering putting this in hal - would that seem 
reasonable? If so, should we discuss the API? This doesn't conflict with 
doing stuff directly via bluez, but it means that applications can 
potentially share information more easily.

Yup. That's straightforward (and again I was considering allowing that 
via hal)

Indeed. As might be obvious by now, I'd kind of like that to end up in 
hal :)
