well true that the mining aspect may be less profitable then buying from a exchange...but this isn't meant to solely be a profit venture. I feel the mining aspect needs to be there to be fully comprehensive. but exchange buying will be covered in the Financial part of the project...already in talks with Oglala Lakota College here to look into a course on Crypto Algorithms, Dynamic Cryptography, etc.
I don't mean to sound rude, but are you sure you are not in danger of pushing your own interests onto the community, rather than focussing on the community needs? I was more trying to point out that something like an exchange or broker framework allows for a much wider spread of interest groups.
