saw great talks yesterday by marty connor (etherboot/gpxe) and Peter Anvin (syslinux). Really neat stuff. I'm going to talk to them (I hope) today about setting up a killer platform with coreboot, seabios, gpxe, and Peter's very cool syslinux that he demo'd; should make a very neat package for you all to try. And booting over http is interestig :-)
