to be clear, I think I'd be even more comfortable with some sort of socially accepted procedure to sign up for really experimental trials done by some non-profit seeing entity. Some sort of procedure where you get several conventional doctors to sign off on, you know, that conventional medicine isn't going to cure you, then sign up for something that looks good, but hasn't been fully tested yet.

I'm just saying, going to a for-profit entity and saying "give me something experimental" and then paying the same on success or failure seems like a pretty bad idea to me.
