Suitable is a difficult question.
LAT was designed for local networks. There is no routing capability in it, and it relies on broadcast functionality to work.
However, if you configure my bridge program for it, it can pass on LAT frames just as well as DECnet, and it works just fine.
And the same goes for MOP, by the way.

I think someone (can't remember who) tried to make a kind of map, where you also could see where in the physical world people were. Don't think it's up to date, though.
I don't see a problem with giving out the list of endpoints that Update as in its bridge.conf program. Do anyone else feel that this would be a problem?

But the bridge program can act as a chain of hops as well. The only restriction is that it don't have anything like STP, so if you create a loop, you are in big trouble.
