A few months ago I fiddled with diskless booting which seems
to work pretty fine with newer NICs that come with a PXE 
boot prom (intel, 3com  cards for example).

all you need is 
pxelinux (part of syslinux
ftp://ftp.kernel.org/pub/linux/utils/boot/syslinux/ )
tftpd from ftp://www.kernel.org/pub/software/network/tftp/
a dhcp server
and nfs (depending on the configuration)

I tried 2 methods:

1) nfs root
   just copied some important directories from an
   existing installation somewhere else where the
   client could mount it rw as /

2) initrd
   copied some things together for a minimal system
   and made a ram disk image. then the client
   works completely from a ram disk which is obtained form
   the server on boottime.

this way it should be possible to have some diskless
clients who share a common video directory on a server
which holds all information ...

well, since I don't have a server I stopped fiddling with it,
at least for now ...
