First hit is http://portablelinuxapps.org/
Now if you find it doesn't work on this distro, why would you have to stick with this distro?

Are there any portable apps for Fedora 17 LXDE?
Specifically, I need a sound recorder.
Currently, I am unable to install any software, as the hard drive is not working; I am running Fedora as a LiveCD.
Any help is appreciated.
