That's brilliant. Is there any way to get a wifi module like this on the Raspberry Pi? All the ones I've found require external power (i.e. a USB hub)...
I've used both of these without a hub without any problem. I use an old Samsung cell charger (I think 700ma). I don't generally have anything else drawing power from the USB port though.

It worked with zero extra setup on my Pi. Plugged directly into Pi - no hub.
