Do true full-dupliex data-over-mains 'modems'

for this years ago seemed to be half-duplex only (it had a
trasnmit-enable input, and you were supposed to only have one
transmiotter enabled at a time out of all the chips on your mains
wiring).And that certainly wouldn't do here.
Hmmm not sure. Although I don't really see why not; coax-based Ethernet's a
"single wire" design and works OK - so I don't see why the same sort of
design
couldn't be done over mains wiring.
Sneakernetting
data around isn't such a problem in a classic context, though -
That depends on how many machins you have to climb over to get between
the 2 you want to connect :-)
True, I've seen your house :-)
The Netcommander sounds interesting - but as you say, it requires extra
cabling. If extra cabling's unavoidable, maybe something like Econet is a
better bet* as you'll have less cabling in total and more capacity (but it
makes the big assumptions that you have an expansion bus you can make use of
on each of your machines, and that you can write protocol software)
* by hanging an Econet module off the back of each machine (rather than
rolling your own around the 68B54 ADLC)
