SIMH V4, as of a while ago.
Is there any advantage over forwarding over a bridged tap device? Performance? Stability?
Ethernet is meant for short distances and very low loss rates. While it (and GRE) will
work across oceans given the modern Internet, performance may not be optimal. That's
especially true with bridged Ethernet if you have lots of stations on the bridge.
DDCMP is specifically for long distance point to point links, and works better than
Ethernet if there is a non-trivial packet loss rate.
I tend to pick DDCMP fairly often even though these points were a lot more valid 40 years
ago than they are today.

SIMH supports the Ethernet over UDP tunnel protocol
It does? I didn't know that. As of which simh version? Can this talk directly to pyDECnet?
Yes, I do this routinely with my RSTS system. I have also connected that via DDCMP,
that's another fine option.
