I agree with the portableapps.com, Haller is prolific if nothing else. In total I currently carry the following on my USB thumbdrive. Torpark, Mozilla Firefox, Miranda, Gaim, Popcorn,QM, ClamWin, Truecrypt, TightVNC, WinRAR, Restoration, FileMon, WinAudit, RockXP, AngryIP Scanner, NVU, VLC Media Player, FileZilla, the Gimp, OpenOffice, 7-Zip, TedNPad, and BareGrep. That's about it.
