IIUC, PXE provides a remote boot image - usually handed out by the
DHCP server.  This is pretty easy to set up (see the edubuntu
packages).

However, I don't understand the next portion.  If you aren't loading
the / filesystem via NFS, where will you load it from?  Even if you
succeed in loading the entire / filesystem into RAM ( going to need a
lot of RAM! ;) via tmpfs, you have to load it from somewhere.  Am I
missing something?
