If the purpose of putting a distro CD/DVD on a usb stick is to have
a very tiny portable installation medim, then installing F13 onto the usb
stick as you would on a normal drive would defeat the aforementioned 
purpose.
That said, I have done both: I have installed the DVD media onto
USB for the purpose of having a tiny and portable linux,
and I have also used  liveusb-creator-3.9.2-1.fc13.noarch
which lets me choose the iso to install onto the usb media.
That has helped me install it on friends' machines when they
had no internet available,

Since you will have a lot of problems doing this on FC7,
I suggest you upgrade to F13 and install liveusb-creator-3.9.2-1.fc13.noarch
