AS for price, as with most things i do, it will be FOSS (free, open source software). Full code will be provided to those who ask in case they want to tweak it / bug fix it, etc..
Point is, i KNOW now its possible to do. And i honestly suspect anythnig with a 2.0+ BT chipset will do it, 2.1+ would be nicer as it has a better paired key exchange. No huge deal, but something to look out for on the compatibility side of things. Theres not many 2.1+ dongles around, so id probably be aiming at 2.0+EDR.
With that theres also 2 options..
These are both linked from sparkfun, so credit to them for the pics. The top one would require some hacking to get it into your MS unit. Its a 1.8v - 3.3v power, and more of a dev thing. The beauty of this solution is total integration, its ALWAYS there / powered on if the MS unit is on, and you can still use your normal RS232 cable + laptop / whatever if you wish.. So you could technically log with BOTH devices (android phone + laptop) at the same time.
With just a dongle, you would have to leave it on, and you would need to power it some how. One way ive thought of is getting a 3.5mm stereo jack, and making a short break out wire to power the sucker. So this still requires some level of modding your MS unit, BUT if you were able to assemble it, im sure you can do this.
I just purchased the dongle - you shouldn't need to do any hacking, other than maybe what's outlined in the megasquirt/bluetooth guide. on V3.0 boards there is already power at pin 9.
