It is up to those who would develop tech, such as the various
'atmosat' approaches, Loon balloon, Aquila solar drone (made in UK),
tropopause or stratospheric Stratobus.

So far, the tech has a long way to go; it seems the developers can't
really decide whether to stay out of the winds by lingering in the
tropopause or to go higher and try to go up and down to catch the
opposing currents to stay in place or float around the world.

For a glance at the 'ups and downs' of advanced altitude comm tech, one
need look no further than the financial fluctuations of the satellite
radio story prior to the current Sirius XM and the even more devastating
fluctuation of the Iridium debacle, which is currently back in business
big-time launching more sats.
