[Gta04-owner] Bluetooth default speed?

Hi,
i have now working bluetooth in debian userspace. You just need to tell 
bluetooth init script to launch hciattach:

	echo "-s 115200 /dev/ttyO0 any 115200 flow" > /etc/bluetooth/uart

But the problem is that e.g. for A2DP audio the default speed (115200) is 
unusable.

I can solve this easily for myself. Increase the speed, store it permanently 
as documented here [1] and do:

	echo "-s 3000000 /dev/ttyO0 any 3000000 flow" > /etc/bluetooth/uart

But from the distribution maker point of view, this is problem. I cant know 
which speed to use. Either i can assume that everyone has slow speed, but then 
the user experience will be bad. Or i can assume that everyone has configured 
bluetooth for high speed.

What is best solution?

To me it looks like best solution to set up high speed for all new devices 
(group tour) and let all existing users set high speed themselves. I can 
supply  /etc/bluetooth/uart with the high speed then...

Regards

Radek
