Can these new payment services beat Paypal?

Recurly, Stripe, Chargify and 1000s more to come. Why will they succeed when Google Checkout, with all that Google-y muscle, hasn’t? Perhaps their ambition is to just carve out a niche for themselves instead of replacing Paypal as the dominant online payment solution. Now that makes sense.

Or perhaps they plan to be behind-the-scenes and do B2B (eg: power the Saas businesses) rather than handle B2C themselves (which requires oodles of user trust that comes from brand recognition).
