On the paypal-right-now thing, the critical, deal-breaker point is that:
Kickstarter won't take your money if the project doesn't reach the goal, but Paypal will take it immediately.
We can't in good conscience take, say, 10% of the money (via paypal, or directly, or whatever) and then just not produce something. And we certainly can't produce the game for only 10% of the money.
So then we'd be stuck trying to do a ton of refunds through paypal and wind up in a worse position than simply not succeeding in funding.
But if we succeed and after we get the KS money, other options definitely make sense.
