Real time mirroring would be a looooong way to go for very little return. You'd be much better off with some sort of NAS in a raid config, even if it were home grown, to store the spools. Then you can have as many front-ends as you want, just auth with LDAP or something. -- Andy Harrison _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
