No. A Toad cannot talk DECnet at all, as far as I am aware. It also do not have Prime

Basically, for the time being, Toads are out of DECnet, in all aspects. They are IP only.
My thinking was that a Toad runs TOPS-20 so it should be able to run DECnet, except for
some details. If a fixed MAC address stands in the way but someone feels like tweaking
DECnet/20 to add Prime support, that would be a way to cure it.
If the difficulties for DECnet/Toad are much larger than that, I suppose this doesn't
really help.

don't think I've ever seen any, so that would boil down to just be able to talk
DECnet to other PyDECnet nodes. Not sure how much value that would have...
Phase IV Prime can only talk to prime neighbors, but via a prime router it can talk to
anything else just like regular Phase IV. So it should be useful; the only limitation is
that you'd need to have a Phase IV prime router adjacency.
Right. And since the only Prime implementation that I am aware of would be the PyDECnet
one, it means you can talk DECnet directly between those, but not to anything else.
However, you can also achieve this by just having GRE, Multinet, or whatever in between
those two nodes, and just use IP.
