I think if you pay him for supporting eSCO, then it will be very quickly
integrated.

Look here:

I don't know whether someone donated anything after this request, but I
think he can't get enought. ;)

I don't know of any...

..but i am quite sure this might be possible. Marcel while probably
reply itself. He is the best suited person, for such a job.

Yeah I understand your problem and IMO you are partly right. There is no
so strict seperation of a testing and a stable tree. But you have to
seperate: the generic ACL/RFCOMM support is quite stable. You can use
it without integrating all those parts which might be considered not
completely stable.
I personaly wouldn't use HID or SCO support in a commercial device.

yes

You mean those -mh patches for 2.6?
