In the footnotes of a recent post Luis Villa says

"fedora makes it very easy to turn a liveCD iso into a USB key (one command line); Ubuntu’s equivalent process is poorly documented and awkward, which is why I haven’t bothered to test a new Ubuntu Tribe as well"

I also found non-VM testing of CD images more convenient when writing them to a 1GB USB stick compared to burning to an actual CD. It's faster to create, does not waste blanks or wear out CDRW-s and it is noticeably faster to boot (no slow seeks in flash memory).

I modified the Fedora script to work with the Ubuntu liveCD layout and put it here

You'll need to run it on an unmounted vfat formatted partition, for ex:
$ sudo ./isotostick.sh /path/to/image.iso /dev/sdb1

It should work on all ubuntu variants since they use the same liveCD layout.
