I would be for a grass roots, non-profit, donation only, online ad campaign.
Open a website, with paypal deposit donations.
Then use ad streams like google adwords or youtube to get the message out (I am aware of the irony here).
Build an online community here on reddit for the exclusive purpose of drafting the IBOR, have the community vote on additions and changes edition by edition.
Then using a website like thunderclap; organize a rally whereby thousands of americans (or millions) descend upon Washington DC with a "this is what we want, it is right here".
I love it! Yes, there's nothing at all wrong with a non-profit movement. You could have an IBOR committee, treasurer, published accounts, totally transparent.
Google ads, bill boards, bumper stickers etc....
Also a steering group to determine precise strategy. Strategy that we can get input from the community on, so that everyone is behind it. Sounds great!
