liveusb-creator: Install Live Operating Systems on a USB Flash Drive

liveusb-creator is an Open Source utility that lets you create live (run-able) operating systems on a USB flash drive. It runs on Microsoft Windows and Linux and has what looks like a nice GUI (no command line magic needed). It looks like it is tuned (will auto-download) for installing Fedora Linux. I'm sitting on an old Fedora 7 box right now (9 is the current release). But, ironically, the PyQt4 Python binding needed won't install from binary on this version of Fedora (haven't tried to install it from source yet).
