I've just discovered that Splashtop 2 combined with Windows 8 supports multi touch gestures and full Win 8 swipe gestures. Been testing it on my nexus 7 and it works flawlessly. Very minor latency on my wireless n network but this has been a very cheap way to try out the windows 8 touch experience and I must admit it isn't bad at all. Before starting I set splashtop to display the screen resolution at 1366*768 so metro applications would work and it has been fine from there. Give it a go if you wanted to see what windows 8 was like on touch and didn't wan to fork out for a surface. As you're connected to an x86 PC, its more akin to surface pro too.
