This was done with gui.  I typed 'liveusb-creator' from command line, enter root 
pw, then select my ISO image from my hard drive, then press 'create usb' (IIRC).

Tried with unallocated space.  Then tried after creating a single partition with 
VFAT (formatted).  This gives a different error:
Fedora-15-x86_64-DVD.iso selected
Verifying filesystem...
Verifying ISO MD5 checksum
ISO MD5 checksum passed
Extracting live image to USB device...
Unable to find LiveOS on ISO
LiveUSB creation failed!
Unable to find LiveOS on ISO

I guess only an iso designed for live will work?  Actually, I was _trying_ to 
use the usb for install, not for live.
