So, I meant to post this up a couple of weeks ago... better late than never.
I have posted an early beta copy of usb-creator package in my PPA. It contains packages for both the gtk and kde front-ends and a common package, which contains the back-end, and some other common bits.
If you are interested in trialing the beta, feel free to download the debs or add my PPA to your sources.list (if you add it to your list, please read the warning on my PPA page).
To get the files, navigate here.
Here are some screenshots showing the kde front-end in action. Enjoy!
