I've been looking over this site for several days and I hope I'm ready to start asking questions...
The reason I found this site is because I want to plug a USB drive into any computer and have it start up Opera automatically.
I'm trying to figure out the difference between PStart (which I did find and put on a drive to look at), and the PortableApps Menu thing you have here (haven't downloaded that one yet).
I've been reading up on autorun and other topics and the result is that I have about 100 more reasons to hate Windows.
In any case, I understand that autorun will probably not work on my system (Windows2000), but I might still be able to get something working on XP. maybe.
I also tried to change the drive name of the USB drive and while it is named "Z" on MY system, what it gets called on another system is anyone's guess.
Have I mentioned I hate Windows???
BTW, I think this whole idea of using portable programs is WAY freakin' cool and I have been playing around with your portable GIMP (which I first learned on my linux system years ago).
