RE: Rural Outsourcing and the Speed of Light

verifies that Geosync orbit is 22,500 miles.  So that is 45,000 miles round
trip (up and back).  The speed of light is about 186,000 miles per second so
the minimum time you could ever have to get a byte from your house to
someplace else is about a quarter second.

Don't know how a ping could ever be less than half a second since the echo
request must go up, down to the other ground station, to its destination, be
replied to, back to ground station, back up, and finally back down to you.

Or is my math all botched up?  

Forget about the speed of all the electronics etc....that 90,000 miles is a
killer!
