I think this:

-A Carbon market featured on GreenCoin.com, where users can buy and sell Carbon - GRE will be traded in the background, but opening up to a wider market will cause the GreenCoin price to be completely reflective of Carbon, and thus will reflect a true open market price for carbon.

would need some more arguments, running an exchange can be quite expansive, I understand your corp is non-profit and you can use the 50% mined only to reward green power producers. Correct? Do you apply for call for tenders for ngos? A part from this (and the Mac wallet:), still not working, I will see if I have some time to compile it on my mac) I love the setup.

Thanks
