Fair enough, then they could make it an option as soon as the project made its 100% goal and it'd be fine too. But for sake of argument, paypal actually allows you to do that in a sort of way. You can request payment after all. And when the one wanting the money does this is his choice. So basically you don't "literally" pledge via paypal, you simply need a confirmed paypal account and "pledge" ie, you declare you are willing to give this and that amount .. Then, once the period is up and the goal is reached, the Kickstarter requests payment and gets funds.
It would require you coding a custom payment system... Although I don't see how this is any different from how Amazon Payments does it. One thing is for sure, Kickstarter is large enough to have someone at Paypal listen to their requests and questions on how to best facilitate the system if they really wanted to ;p
The only reason I (half) know how this could work, is because certain kickstarter "clones" support paypal sort of like that.
That said, once paypal is up for this I'll be supporting this as well. It just doesn't count into the kickstart totals until way at the end... ;/
