It's a little half-baked, IMHO, when they talk about making this available to the public. They even mention The Smithsonian, but we already have a copy of the constitution on display at the National Archives Museum in DC.
Overall, it sounds like a fun project and I'd be curious to see how things work out if they do end up getting it, but it doesn't sound like anything I'd want to put my money into.
I predict that they'll eventually sell it for a profit.
