Here's a way you can run Linux off your USB Flash, I haven't tried it yet. (My sister doesn't trust me enough to mess with hers, and I'm saving up for a 512mb stick so I can go really insane with the Portable Linux) But it works well in theory, and this guy has done it.

Enjoy! Please post your experiences with this if you've done something crazy and fun like this before, or tried this out.
