I'm very much a libertarian, pro-gun kind of guy and I'm glad this project project exists, but I do have to say I'm reluctant about it. There isn't really anything (that I can see) that can stop this movement. I abhor gun registries and most restrictions on firearms but I'm glad that there is at least a small hurdle to acquiring a firearm (purchase permits). Hopefully the trend towards more and more CCW holders increases as responsible people carrying guns will be a big line of defense against crazy people. See: http://www.reddit.com/r/dgu for a sampling of recent defensive gun uses, it is a very common occurance.
Michigan use to require a purchase permit for pistols. You had to go to the Michigan State Police, take a little quiz, and they would issue you a purchase permit. The permit had an expiration date. You bought the pistol with the permit and then had to take the pistol back to the police station for a safety check.
