can NIS actually preserve shadow-ness of passwords?  I would 
never run a cluster that exposed encrypted passwords.

for small clusters, I would definitely use nfs-root;
for larger ones, probably ldap.  having a cron job run 
rsync frequently isn't a terrible solution, though,
especially if there's one canonical node (a login node)
where the only changes are made.
