I talked with Marcel about this. Here's the current situation:
uart-connected bluetooth adapters can do multiple sco connections
without any trouble.
usb-connected bluetooth adapters suffer from a limitation in the usb
kernel layer... the number of sco connections has to be hardcoded at
boot time in the isoc parameter. If it's set for two 16-bit sco
connections, when more or fewer connections are in use, no audio gets
through. The usb layer needs a rewrite to fix this.
