Article: Tutorial on How to access your PC from work
An article from iMod on how to use a USB drive to access files on your home PC, and run programs remotely. I'm imagining all sorts of possibilities (excluding what an excellent April Fool's Joke it'd make to surprise my poor wife at home, LOL). Imagine being able to access work files, pictures and articles from home - brilliant.
All that is needed is a USB thumb drive and a program called UltraVNC. The tutorial details how the settings on UltraVNC for the fun to begin.
Part 2 of the article (just scroll down abit on the page), is also interesting as you could download a custom USB setup containing the author's favourite USB applications. My eyes gleamed when I saw the portable SNES emulator :)
