Great detail Mike. Altitude does make a difference.
As to the hosting idea. With that many domes, you'll need a lot more money than we spent at Swan Reach Imaging; and that was a bucket load. On top of that I did about $70k worth of work to minimise labour costs. Domes are sexy but not practical really, not to mention they can be very buggy. And; yes it is a really big commitment. Work starts half an hour before sunset every night, but I don't want to discourage you.
