Its actually very easy to make something autorun, I used to burn digital pictures on to a mini CD then make a simple slideshow program autorun when the CD was inserted. Flash drives would be even easier since they can be written to, or you could have a macro virus embedded into your default template in MS Word which attaches to all the word documents you put on the flash drive then when someone else opens one it attaches to the template on their PC (on reason I've switched to open office on my personal system).
Hmm, slax sounds like slackware, wonder if thats what its based on. I'm running slackware and my mp3 computer in the truck runs it from a 128M read only CF card plugged into the primary IDE port.
