The website is still being updated to handle the user privileges but I can share the new documentation and release notes with everyone
Documentation: (see USB Client)

Release Notes:
http://www.tinyclr.com/release-notes-beta/
This code emulates a USB mouse and moves it in a circle…This is how you can freak out your friends, wife and kids…put this program on FEZ and make the mouse movement run randomly every few minutes. Then plug FEZ behind someone’s computer. While they are using the computer, the mouse will start going in a circle on its own…“oh my god! it is a ghost!!!” 
If you actually tried this trick on someone, please let us know how much fun you had 
Have fun…
