Let me see if I understand you correctly: each node initially boots
from floppy and then goes through a sort of second-stage boot that
sets up the ramdisk, etc., is that right?  So a local floppy disk is
required on every node?

Have you ever tried doing this with PXE?  Or does the PXE reliance on
tftp (even multicast tftp) make it undesirable?
