i've never seen that before. At a guess it would take a virtual interface that dynamically enables whichever bit of hardware is to be favored. e.g. Use the wired if connected, otherwise use the wireless.

As I said, never seen that before.

It's called a "bridge device" under Linux.

Basically, configure the wireless i/f and the wired i/f as members of a bridge, and assign a single IP address to the bridge itself, rather than to the member interfaces.

I'm sure that MS must have heard of this kind of thing already, right?
Linux has had it for (many) years already.
