they haven't been implemented yet though, I think That's kind of a show-stopper, then. Saying that Bitcoin is an alternative to Paypal for these kind of Kickstarter-like efforts is just disingenuous and exposing your "customers" needlessly.

  They're in the protocol, no one's used them yet.

  Well, USD doesn't have that feature either, but we have central agencies we trust (e.g. kickstarter). There's no reason why that model cannot be used with Bitcoin (so nothing disingenuous as you claim). The real power of Bitcoin would be to be able to do this in a trust-less manner. It hasn't been implemented yet, but exists in the Bitcoin Protocol. You're welcome to take a shot at it, by the way, the core developer team is always looking for new developers.

So using PayPal as the central agency on Bitcoin would be exactly the same, and using a different central agency is a change independent of the use of Bitcoin.

I don't know that 'Bitcoin has X if you write code to let Bitcoin do X' is quite the same as 'Bitcoin has X.' Lots of things can do X if I put in all the work to do X.
