Windows Phone 7 demo shows cross platform game coding, playing

Here is another very interesting demo from TechEd Middle East.  It shows a game being started on the desktop, continued on the Windows phone 7 and then finished on an XBox.

It also shows the coding process, including a glimpse of the sensor framework, and the promise that 90% of the code, presumably Silverlight and XNA, can be shared between the platforms.
