Otherwise known as the "voting machine company was too stupid to implement SSL" attack?
Or, for email, the "what idiot thinks email is secure without local S/MIME or PGP signatures" attack. Seriously, on-wire tampering is the least if your worries if you're *emailing* ballots around.
You forgot to mention that he has an embarrassingly small sample size and doesn't do any sample correction. He doesn't publish any significance values, so we have no way of knowing if 70% is the same or different than 77%, to the accuracy of the methodology (as well or as poorly thought out as it may be). Then he considers 86% and 67% to be about the same, and subsequently 63% and 79% to be about the same.
I am not a professional statistician -- I hire people to do that sort of work for me when I need definitive answers because I don't know the details. But I know enough to recognize handwaving, and that's all the long-winded original posting is.
I think the guesstimates that some sort of immortality might be within our reach within 3-5 decades are overly optimistic. I'm also fairly pessimistic that they'd be available to everyone when they finally do come around. The top 1 to 5 percent might be able to afford to extend their lives. The other 10+ billion people will be on the planet by then will probably resent that. Should make for some interesting times that I really don't expect to be around to witness.
I bet you could put together a software satellite simulator to test your design for significantly less than what it'd cost to launch one satellite. The math to describe an orbit isn't particularly hard -- it's basically just trig. Put a couple dozen fake birds in fake orbit, set up your fake antennas on the ground and start pushing fake packets between them. No sense in building a rocket if that tells you it's not going to work.
