Bluetooth DUN is the same, just that you would need a poke at hcid's
D-Bus interface telling it to create an rfcomm device for you. eg.
- Find the serial service using org.bluez.Manager.ListServices()
- ConnectService(<bluetooth address>, "DUN")

You get a device from ConnectService, and use that to connect. You need
to clean up when you disconnect though, DisconnectService(device)

Yep.

Yep, that's possible as well.
