Linux and FreeBSD mask these entry points pretty well by using the standard
socket API (although only Linux supports SCO links at this stage due to
FreeBSD having some problems with isochronous transfers that are being
worked on).
It doesn't matter too much whether Apple decide to expose SCO as an
audio driver or a raw stream, as long as the more interesting Bluetooth
profiles can be implemented with the result; I'm especially interested
in Handsfree.
