And I should mention that I couldn't have done it without Paul's help.

The fact that the bridge turns everything into a single Ethernet
segment is one of the reasons why I wrote my own user mode router. It
interoperates with the bridge and also SIMH DDCMP (although I haven't
tried that for a while and it looks like I haven't documented the fact either!).

I should mention that Rob's work was what inspired PyDECnet.

All the negative comments I?ve seen about Multinet...
I?ve never had a problem with it, connecting nodes across the Internet via
TCP.
Yes, it often can look ok.
Part of my dislike of it comes from the fact that it is obvious it was created by
people who had never paid serious attention to the DECnet architecture
specifications. And part of it comes from the hacks and workarounds I needed
to make in PyDECnet to get it to work -- for some definition of "work". The
need for those hacks is a direct consequence of the ignorance of the Multinet
designers.
I know from experience it can never be truly reliable in the sense of dealing
well with nodes restarting or flaky networks. The most I can possibly do is work
around its fundamental design errors to the point that links will, in general,
come up eventually and will stay up if the winds are fair.
