No, it's fact. Try managing a remote system in a X-window via satellite.
Poo-poo doesn't even begin to describe it. If your window is remote too
it's even worse. Only a small portion of that is down to X's ack/nak
protocol. Or try playing a networked game over a satellite - forget it.

Well, duh. Why should people face that choice? Run fibre. Everywhere.

Not only is it tenable, it's a good solution, and one that would have
far-reaching benefits for the country as a whole. NOT just for the
"remote recipients of the cities' largess" as some people are painting
it.

Never said it was. But they have double the latency. And even one-way
has too much latency.

Such places are very very few. If there's a road, there should be fibre.
If there's power or rail, there DEFINITELY should be fibre.

100% coverage may not be possible. But for goodness' sake, it should at
least be our aim!

Vision, people. Vision.
