Not sure what you mean by "handle DECnet as cluster".
But before LAVC, the only way to cluster was over CI, which simh do not 
emulate. So, if you want any kind of cluster, you *have* to do it over 
ethernet, which means you need at minimum VMS V5.5-H2.

There is no CI to Ethernet adapter. It is two different network 
technologies, with no easy translation between them.

That should work just fine, as long as you have a VMS cluster.
