[K12OSN] OpenMosix cluster

[Dennis Daniels]

Using XDMCP chooser, though rarely discussed, stands to be a much better 
solution for the low-budget folks... you can set up mutltiple servers on 
the same network and have users access their folders via NFS. Now it 
sounds great but FC2 /K12 4.1 has problems with XDM/KDM and GDM. Take a 
look at the docs here and give it a shot... you might have more luck on 
a slim budget with XDMCP than with mosix, thouhgh YMMV.
best of luck and report back!
