Nothing's set up. If you happen to catch Captain DJ around, you might be able to sway him into integrating others. I know he's considered BitCoin, for example, for what that's worth.
The major issue (I'm not speaking for him, but from my own, low-end e-commerce experience) is probably that, despite strides made by other companies, PayPal is still--by far--pretty much the easiest processor to integrate with a website.
Also, it's worth pointing out that PayPal doesn't require an account, and you can use them with pretty much any card. And, I'd imagine, a gift Visa or something would work.
