The problem with making every machine a slave (which we have tried) is
that eventually the periodic yppusshes themselves load down the net--plus
you still get timeouts even then.
Here at Fermilab we have found that NIS starts breaking down when you
have about 100-150 nodes. We are moving to a system of shoving out
password files with rdist..although our situation is easier than
most because we don't have to push every time someone changes
a password--these are handled with Kerberos.
