Spotted elsewhere, but Stevecla is where I first saw this great demonstration of a game running across a Win7 PC, A Windows Phone 7 Series device and an XBox. It’ll never catch on :)

Talking of phones (which we sort of were), worth a look at Charlie’s post on the Windows Phone Developer Blog, and his list of those contributing which bits. The full session list for Windows Phone development at  MIX has now been published too. Yum yum.
