Jav,

I'm not familiar with the VMS clustering behavior -- what services does it
provide?  NIS can certainly provide an (insecure) password/etc sharing
option under FreeBSD, although personally I make use of Kerberos and use a
distributed file system for moving password files/etc around.  I have
always found the concept of Hesiod appealing -- especially now that DNSsec
seems to be working out.  The Athena secure DNS (via kerberos) concept
never did much for me, though.

None of these solutions are particularly transparent, though -- perhaps
having a shared /etc/usefulfiles and working NFS locking (and a few other
snippets) would be a reasonable answer for small-scale clustering.
