Regarding the ability to read Microsoft Tags displayed in a touch screen -- yes! You should be able to perform similar actions on any Windows machine. All you have to do is generate a unique tag for the content you want to link to it (Check the Microsoft Tag API here), and then scan the tag on your smartphone of choice. (tag reader available for most phones out there).
The Microsoft Surface Toolkit for Windows Touch Beta will work on any Windows 7 Touch PC hardware. If the driver for the specific machine is properly written, the toolkit should work on top of that machine.
