guys, i have been thanking about few ideas about bluetooth headset for N900. However, i am no tech expert, therefore please tell me if i am day-dreaming.

one of the ideas is about using bluetooth headse as an wireless storage. i understand bluetooth headset only support HFP, HSP, or A2DP profiles. however for each bluetooth headset, there is flash for the firmware on board, right? can it be modified to add more profile to support file transfer?

2nd, the is flash to contain firmware for the headset, normally how big is it? can it store any files or programs? and can we modify it or build an interface to allow file management? then how hard to get addional flash memory onto it?

if i am day-dreaming here, please laugh loudly and let me know, also educate me that the design, limitations of bluetooth headset, and how its firmware works with hardware.

many thanks.
