The devkit comes with a power cord that you can plug into the device.
You unclip the power pins to plug it in. That's probably not what you
meant by 'separating the power supply', but at least it doesn't need
to be plugged directly into a socket at all times.

I agree it would make the device quite a bit more useful if it had
those inbuilt. I'm going to use a USB->Wireless dongle or an
Ethernet-Wireless bridge for IP communication which, as you say,
eliminates some of the the benefits of wall-plugness.
