Skepticism aside, why not just prototype and produce what you have, after testing and then mention and offer it to the public?
I feel like unique and useful things usually find their place in the market on their own, with basic advertising.
I have a few ideas of my own that I've blueprinted, but I'm not going to set up camp until I've got something in hand that I know works well and I've used long enough to refine on my own, along with a few guinea pig giveaways.
Its hard to keep an audience in the era of vaporware. Not saying that there is or will be nothing, here, but that is usually the case, so people wait and become disinterested by the time the product is ready for delivery.
I've seen a few publicly funded projects go south, because of testing hang ups in the middle of group buys.
Even Jamie over at Passon had a ton of people flogging him and he had some serious amount of product to show.
From one designer to another, take my humble advice and just be careful not to jump the gun.
