It just occurred to me that you will have to look into these matters anyway.

TCP/IP services 10.5 will be based on Multinet, and Multinet has a PWIP 
driver.

DECnet-Plus is build on top of the PWIP driver, so you will have to 
check if the Multinet PWIP driver is DECnet-Plus compatible, or perhaps 
use the HPE PWIP driver?

Multinet also has a full blown IPv6 implementation, does that also apply 
to their PWIP driver?

Interesting issues to sort out for VSI.
