Finally decided to try and find out what if there was any problem with the portableapps installer/launcher/menu as was insinuated here. Did 2 yahoo searches: "Problem with portableapps installer" "Problems with portableapps". The only thing I found were problems in getting particular apps to install with the installer. Many of those posts were on portableapps own forum. Theoretically, portableapps can run any open source portable. On the other hand, it apparently won't work with any commericial portable that they don't have an agreement with. Seems it recognizes trademarks.
The only other thing I found on that were pages recommending PortableApps. Maybe because I didn't Google. :)
It was hardly a total loss, though. Found a bunch more interesting links. Obviously, there'll be some duplication.

2 2005-2006 articles on running XP completely form a portable. The first is designed to strip down XP to run on a 256Meg, but you can ignore a lot of that unless you want it on one that small:

Moka5, another free solution which allows you to create a virtual PC environment from your USB drive. I assume this is similar to ThinApp's approach. Also in German, and also English Mac OS X. At least the virtual software seems to be free. Moka5 is selling something, but I haven't figured it out:
