There are actually a number of TCP/IP implementations for VMS and at least
a couple of DECnet implementations available for Suns.  In addition to
SunLink/DNI, Thursby Software (Arlington, TX) has a DECnet for SunOS (and a
few other UNIXs), and KI Research makes a DECnet and MOP for several UNIX
platforms (not sure if that includes SunOS, though).

The TCP/IPs for VMS that I am aware of (listed in alphabetical order) are:

Board-based:
------------
	CMC
	EXOS from Excelan/Novell
	Interlan

Host-based:
-----------
	CMU/TEK from Carnegie Mellon University
	Fusion from Network Research Corporation
	MultiNet from TGV, Inc.
	TCPware from Process Software
	WIN/TCP from The Wollongong Group

If you fire off a query to info-vax (probably the best place), I'm sure you
can get some recommendations from users as to the good and bad points of
each of the above VMS TCP/IPs.
