Yes, thanks for the link.
The way to get the altitude effect is to remove some of the O2 from the
room but keep the total pressure the same.
The real trick is to convince the GF or wife to sleep in the altitude
tent with a wacko citizen racer ;-) Let me know if you solve that one.

Good point Bob. Here's a link to altitiude vs. pressure:http://www.engineeringtoolbox.com/air-altitude-pressure-d_462.html
sea level 14.696 psia
3000 ft asl 13.17 psia
5000 ft asl 12.23 psia
7000 ft asl 11.34 psia
I agree that using a gas mixture to bring the O2 to lower amounts
while keeping N2 at the same level should work well for compenstating
the pressure. However, at true altitude the ratio of O2 to N2 remains
the same. I am sure they have done studies showing that changing the
ratio of O2 to N2 is safe, but still. That is why I like the idea of
negative pressure better.
The link below confirms that I was basically full of crap saying that
foil should withstand the pressure. This link says "sturdy walls" are
required.
