[e2e] TCP in outer space

[David P. Reed]

Remember that geosynchronous satellites are indeed far away - .25 second 
RTT.  (as are the moon and planetary missions)

But the discussion didn't start there, but with the International Space 
Station.  ISS, the shuttles, and other LEO stations are essentially no 
different than terrestrial targets - anything that works well on 
transcontinental wired links works for them (they are much closer than many 
earthbound endpoints, at least when they are in line-of-sight).
