I think USB sticks will become much more usable when Fedora allows booting
from iso images like some other distributions already do. Currently the
standard way involves completely overwriting everything on the stick (1
distribution per stick).
Personally I install grub on the stick, extract the contents of the iso
into a directory and manually adjust grub to match (so I now have an
i686/x86_64, f16-f18, KDE Live/DVD USB sick). Seems to me it should be
possible to simplify this a lot (install grub, copy iso, boot) so that USB
sticks are usable by the masses without having to dedicate an entire stick
to the task.
