These are all things I wasn't even thinking of. They would be great reward tiers. I would love to send a little data logger into space just so I could have my own personal data from space, kind of like the ArduSat Kickstarter. I'm not sure if it would be feasible, but if the price was under $1k for a smartphone sized package I'd go for it. Even if it was timesharing my code with someone else's to make it feasible. I'd pay more for a higher chance of success, but given the two year lead time and unknown chance of success I'd want a discount.
