I've never heard of two capsule endoscopes recording each other's data. That's definitely a first, and pretty funny at that. I wouldn't have even thought of it. I'm surprised that so many people haven't even heard of capsule endoscopy before. If you look at my user name and the history of the Wikipedia article, you can see that I worked on the article before. I have Crohn's disease myself, but I've only had a colonoscopy and didn't need a scope for my whole digestive system. I have known many people, however, who have taken the bait and swallowed the pill. It seems like a much more comfortable alternative, but I guess my insurance company wouldn't allow it or it's too expensive to be used in place of all scopes at the moment.
