Bitcoin might be a way around this.

Also it might not be necessary for the involved parties to get together. They could release different protocols. And then the lesser used will be forgotten (like gopher is forgotten today) and the more frequent used will survive (like http has survived).

Update: Why the downvotes?

Well, the point of those payment systems is to make money out of fees and basically control the whole system. You cannot do that with decentralized payment methods.

Most people either haven't heard of Bitcoin or regard Bitcoins as "internet fun bux". It's not happening (at least, not in 2014).
