I met with the founder last week, and seems to be still figuring out the mission statement of this project. Complementary exchange protocols are interesting, but Gillaume may direct his organization to focus more on the real world issue of how to divert spare capacity to non-profit organizations, by creating Non-Profit Script, or a special purpose LETsystem for non-profits.
Because of the special needs of non-profit donators (in-kind donations, tax record keeping, etc), and because the non-profit community may be more open to the late adopting money crowd, I think there is space for this good cause.
A different mission completely, and just as interesting. It's less technology oriented (creating solutions looking for a problem), and focused on a subset of the world's troubles to solve. I'll report on their activities when they finally settle on their direction.
