My understanding is that somewhere along the path you're going to run into a 
device that does not handle DECnet.  Perhaps every device you run into.  You'd 
need IP addresses to even reach remote systems.

Perhaps an IP tunnel would work.  Not familiar with that.

Multinet is reputed to route DECnet using IP packets, I've been told.  Never 
used it myself.

While I don't recommend phase V, I'm told it will route using IP.

I guess it depends upon your intentions, however, using TCP/IP you should be 
able to talk between the systems.  But not phase IV DECnet.

Me, I'd much prefer V7.3 over earlier versions.  V7.2 I believe enhanced 
directory operations.
