I don't use PortableApps itself, but I hacked together my own portable collection of stuff. Together with a portable Launchy, a portable Total Commander, and a few batch files which automatically set environment variables to point to the current location of my Dropbox folder, meaning Launchy knows how to launch all of my software automatically, and in Total Commander, all my directory favorites (ctrl+d) work automagically.
