Two friends and I are working on exactly this! Would love to talk. I'll PM you with my contact info.

Another good place to start understanding the (dis)incentives in US healthcare pricing is Time magazine's "The Bitter Pill" http://www.time.com/time/magazine/article/0,9171,2136864,00..... Though it's important to note it's not just a US -> abroad market, it's a many-many graph. People travel for cost, procedure availability, doctor specialization, for the experience of travel, etc.

If anyone is interested in talking and passionate about this topic, I'd be happy to treat you to coffee with my co-founder and I in downtown SF. Feel free to email me, my email is in my HN profile.
