Wireless Adapter Mainboard dongle - pairable With other Bluetooth device?

[Marsupial]

In the latest update #44 there is talk of an off campaign wireless dongle to attack to commodore computers to enable communication with a wireless blingbox or keyboard.

Would this dongle be able to handle additional Bluetooth device such as joystick?

Would it be pairable with other Bluetooth keyboards?

Thanks for any upcoming info on this, it seems like another exciting product.
