I suppose it's not too likely. The bluetooth dongles probably only hook to a USB master, not a USB slave (i wonder?), and despite open source Linux code could be located that does bluetooth it's going to be operating as a USB master I would expect...
Stiill, that would be a REALLY cool feature...
Though I have an Archos JukeBoxRecorder 20, perhaps there are some newer recorder devices that can already do bluetooth???
