What about the other way round.
Installing Fedora from an NFS but boot it from an USB disk? ;)
Someone is working on a "Booting from a USB Disk HOWTO" for the LDP. I believe the doc is very much a work-in-progress, but you can find it here:

See if that helps you. Alternately, search the public archives of the LDP's "discuss" mailing list for this very topic... that doc generated a bit of useful discussion and some pointers to additional resources.
