Unix on a VAXCluster ??

Chris Torek has started a rumor:  "Ultrix 3.0 will support clusters".  Now,
what does this really mean?  What would we WANT it to mean?  Some ideas:

1/ use of CI bus for Ultrix networking, including NFS
2/ private (mounted by 1 cpu only) Ultrix-format volumes on an HSC
   (shared access through NFS, of course)
3/ directly shared Ultrix-format volumes on an HSC
4/ access to Files-11 volumes on an HSC, presumably shared with other
   VMS nodes in the cluster
5/ complete cluster membership, including shared files and all other
   cluster-global resources
6/ something else

I'm sure the rumor doesn't mean (5).  My guess is that the rumor means
(1) or perhaps (1+2).  Can anyone comment who knows more than Chris
and I do?
