Fair enough.

Although, I did mean that in the context of Hugh's belief
they'd use the RTX2000 for the power grid.  I really can't
see most businesses choosing a solution which might be
harder or costlier for them to maintain.  I guess the lack
of programmers for Forth, and even smaller group of hackers
who would attack Forth systems, could be considered a
"security" feature ...  Of course, it's very possible that
US laws might, currently or in the future, force them to
take protections against terrorist or world wars.

Yes, I was thinking hydrocarbon gas.  Although, steam is a gas ...
So, is it still a gas pipepline?  :-)

A relative had to do much the same when living in New York city
in a building with steam heat.

Supposedly, the air conditioning in an old urban building of a
former employer, now demolished, ran on city supplied steam.
