Ok,

So we know that there are people interested in getting BT SCO
transfers working and that myself and Mike (above) both think that it
would be sufficient to get them working to userland so that they can
then either be routed to the audio system by userland programs or
handled in other ways.

I think if Maksim has code that works through a socket method to
deliver/receive the bt sco data to/from userland that just getting it
into the source tree is all that will be needed for others to develop
the applications to do useful things with that data.

What do we need to do to either test the code out or get it comitted?
I think this is a really important feature that FreeBSD needs to
support for completeness of the bluetooth spec!

If help is needed to test, debug, and/or write code, let me know!

Thanks!
