This doesn't make any sense as an interface, would you have "interface

As a bus name, you might do something like this. I'm guessing you meant

There is probably no point having a unique bus name for every device, if
you already have a unique path. The bus name is used to locate your
process, the path is used to locate an object inside the process.
If this is confusing, it's explained in several places in different ways
(dbus tutorial and I believe the FAQ), maybe one of these is clearer.
In general you can think:
bus name = hostname
unique bus name = IP address
interface = interface (in a programming language, e.g. Java)
object path = pointer / object reference

I would suggest just have an object with a ListDevices() method, which
returns a list of the object paths of the devices.
