it would be great to have an app that allows to connect 2 bluetoothheadsets to the n900 so that 2 persons can talk with each other through the headsets.
This would be great e.g. for talking with your pillion passanger on motorbike.
Some bluetooth headsets take long distances so you might even talk to a person on an other motorbike or an other car (good for driving school).

Also there are a lot of functions that would make such an app even more usefull:
-possibility to connect more than 2 headsets
-the option that the headsets are generaly muted and only send signals when sound is over a (adjustable) level. So there would not always be noise of the airstream
-listening to music (also good when jogging so that all people can here the same)
-navi on n900 sends announcements to one or all of the headsets
-(de-)activating functions by voice-order

-Phone Calls (chooseable wheter functions are for all or only for one headset):
incomming call is accepted after short time of ringing or can be accepted by voice-order


I'm sure there are functions that would make such an app even more usefull and i'm interested in hearing your ideas.
Also there might be other fields to use this app.

I am not able to create such an app but hope to find someone that sees that many people may like this and creates the app.

Maybe the Mainfunction (connect 2 Bluetooth headsets to talk with each other, without the other functions) isn't much work? I dont know at all...
