It's arguable whether the variants are actually ethernet or not. You can get
ethernet range extenders, and if you're using thin-net you can usually get
across an urban street or rural campus with them.
None of these protocols, however, will work if you plug it into a standard
10/100bT hub. For distance, you need a "modem" or an interface device that
efectively does the same thing as a modem; one at each end in fact.
(You're quite right that subsets of the ethernet standard are prevelant in
other transport protocols - why re-invent the wheel - but that doesn't make
them ethernet.)
