you won't be able to have more than three sco connections
simultaneously through one bluetooth adapter. If your bluetooth
adapter is usb-connected it will take a kernel patch to get multiple
simultaneous connections. If it's uart-connected (typical for
embedded) then it will work without patching.
either way you will be writing your own userspace software to copy
audio around and negotiate connections.
