If so, then the next challenge will be getting one of those matches to donate. Per article on HN yesterday, "more than 50 percent of South Asians in the registry refuse to go through with the donation process if selected" (Source: http://www.good.is/post/amit-gupta-and-the-south-asian-bone-... )
If payment improves that ratio, then I would think this could still potentially help Amit.
What's my marrow worth to me? Probably not much; a bit of time and discomfort but overall not a huge deal. However, for the buyer, it's the matter of life or death. Seems like it would be easy to extort someone who needs it.
This is one of the rare cases where I hope the market is very heavily regulated -- say, "Bone marrow is worth $1k. It's illegal to ask for more."
The plasma payment model works just fine, I say try it for other things that are renewable.
Modern marrow collection techniques generally put the donor at low risk, and marrow is renewable, so it appears to be a clear win.
