2. Kickstarter money is technically a donation, so you can spend the money right away if you need to. (taking a typical pre-order is little tricky from an accounting perspective if it's considered revenue)
Donation is the wrong way to think of it from an accounting perspective (though perhaps not from a legal recourse perspective.) Preorders are not recognized as revenue. They are a debit (increase) to Cash and a credit (increase) to a liability that's usually Unearned Revenue. As you ship, you credit (increase) Revenue/Sales and then debit (decrease) the Unearned Revenue liability account.
Edit: renamed 'Prepaid' to 'Unearned' -- had to brush up on my GAAP nomenclature
Just in terms of law: it's not an investment, it's not a purchase (since there's no guarantee of backers receiving their rewards), it's not a loan. It works exactly like when your local public radio station offers t-shirts to donors. IANAL but it seems pretty clear that kickstarter revenue would be a donation from a legal perspective.
As a backer, I'd treat Kickstarter just like setting the money on fire.
As a project, I'd be unlikely to offer a complicated physical device that I was not yet able to produce. I might put weaselly bullshit about a reward being a great sticker and up to 1 device.
I think the actual litigation that has already occurred -- e.g., the Washington State and FTC consumer protection suits -- have treated it mostly as a purchase (money exchange for a specific obligation), and certainly not as a donation.
It's certainly not portrayed as a pure donation (money given with no specific reciprocal commitment) in Kickstarter's terms.
