My somewhat educated guess... possible? Maybe. Practical? Maybe not, since for each BOH you would need to cannibalize one DVB dongle (of the right kind, that is), possibly shield it and also provide it with at least an adequate antenna probably sticking out of the BOH's side.

All that aside, I still like your idea!

As a vaguely related thought, I wonder if someone has tested how well (or poorly) SDR Touch works on Alien Dalvik?
