H120 + serial<->bluetooth module

[p.tomczyk]

Hi forum!

have idea: serial<->bluetooth module (3.3v) connected to H120's rs232 pad, speaking with other end (PC with bluetooth) using MPD protocol.
can anyone think of some impediments?

BT module probably will have to stay outside of case, as its magnesium and will probably shield the signal. and I'd have to implement (partial) MPD protocol for rockbox on serial line, but it's definitely doable, right?

(BT module - something like this: http://www.instructables.com/id/Cheap-2-Way-Bluetooth-Connection-Between-Arduino-a/step3/Wiring-the-Arduino-Bluetooth-transceiver/ )
