I think someone who understands the PXE/etherboot process better than I
do could install DRBL on a k12ltsp server, then patch the boot choices
together so certain machine types (based on mac address ranges) would
continue to boot as thin clients while others (with more RAM, faster
CPU, etc.) would boot as diskless 'fat' clients with an NFS-mounted root
and everything running locally, getting the same home directory either
way. (But don't try this on a production server unless you know what
you are doing...). It would at least make an interesting comparison for
where the 'fat' approach is better.

The clonezilla-live CD has a netboot option on its boot menu that should
work well enough for testing the concept on machines that won't do PXE.
It is supposed to be easy to remaster that CD.
