I don't have first hand information regarding this matter myself, but
according to SBC wikipedia page [1]:
"The patent owners wrote that they allow the free usage of SBC in Bluetooth 
application, with the view to boost the use of this technology. All 
applications outside Bluetooth are however not free."

So having SBC codec tightly coupled with bluez at least makes some sense. From
purely technical point of view, a standalone library could be better.
