If Dishy can do beamforming to have a radio signal hit a fast moving satellite several hundred kilometers away, in space -- then couldn't two or more Dishies be repurposed/reprogrammed -- to create point-to-point line-of-sight terrestrial Internet links -- a wireless mesh network -- on the ground -- covering long distances? You know, if there's ever a Zombie Apocalypse -- and Starlink for whatever reason, becomes unavailable... Of course, we hope it never happens... but it seems like two or more repurposed Dishies -- would make a great Internet bridge (or wireless mesh segment) over long line-of-sight distances -- on the ground... Also, multiple dishies in space, at different distances from the Earth, acting as repeaters -- might make a great future way to get Internet (and other space-related communications) to the Moon or Mars or beyond...
