According to the economist it can. There is a new trend of non profit ipo's being released for public trading. Its an attempt to improve the way charity and other philanthropic enterprises generate revenue for their respective causes.
Heres the link to the article for review: http://www.economist.com/node/12208564
As far as the exact requirements I looked into ipo release and the process is usually once the company is filed and legal they have a sit down with a major investment firm where the agree to terms of a certain amount of shares to that investment firm followed by the total amount of shares available for trade. I suppose the business plan is reviewed and if everything goes smoothly it will go out for initial public release.
There are all kinds of silly ipo's that have been released in the past so I can't imagine it to be impossible for a non profit charitable organization promoting a private economic sector with invested interests in middle America to lend its services and name to the public.
Because of this I am fully aware of the amount of work it will take to get this project off the ground and am turning to private investors to help kick start our cause and help build a name for our group. Money breeds respect and so does success so I urge investors to help our cause if not simply for the Advertisements but for the bitcoin and small businesses in general.
I released a new video discussing this very topic and an overview of research topics today. Check it out here: http://www.youtube.com/watch?v=v7pR1CCXxno
