If DEC had embraced IP, and migrated the DECnet capabilities to IP, we'd all be
much better off.
Now, if there were some needs for OSI, then implelment that, but, not the whole
DECnet thingy.

Odd, other then your "Phase IV must die", and Steve being controversial, I don't
think that I've seen much of that issue.
Michael has stated that he doesn't think VSI will want to break anything.
It appears that VSI most likely keep the special DECnet IV transport over IP.
It's highly likely the DECnet V over IP will continue to function.
As I've written above, we'd all have been better off if DEC had implemented the
useful functionality of DECnet in IP. But "now is now", and it's up to VSI and
/ or contributors to perform such implementation, should they choose to do so.
VSI will follow the PAYING customers, as they should. Have you made an offer to
VSI to do some contributions, such as FAL over IP?

The issue of "paying customer" comes up, again ....

Now that can be laid at the feet of HP how milked the VMS cow without bothering
to feed it for some years. Yes, IPSEC is something that should be mandatory,
and I'm betting VSI will provide it. Going to make a lot of people rather happy.
Speaking for myself, it's my opinion that transmission security is a network
problem, and for some cases IPSEC is the optimal solution.

Frankly, with perhaps maybe a small iota of time, I doubt DECnet is going to
need much work to keep the current functionality. And I think most will agree
that any other work on DECnet is a waste of critically needed resources.
Now, IPv6 should become standard in VMS, and I'd say ALL of VMS. DECnet is part
of VMS.

Yes, use DECnet as needed, until better comes along. That's both IV and V ..
