Far too many "Paypal killers" coming about which lack one thing that could actually help them usurp Paypal...international support.

Stripe, Weepay, Samurai - all look amazing, but it is SO frustrating to seem them all release their products and pretend they can challenge the likes of Paypal whilst disregarding the rest of the world.

I know people are promising international support, but are they really going to make the jump after everything gets all cosy with a US only audience?

I've recently deployed 2checkout (I'm UK based). It's not pretty and it's not fully integrated with an API, but it's damn easy, doesn't require Merchant accounts and people can pay you with credit cards or Paypal.
