I've heard of one called RevolutionMoney (I think) that people are saying is showing promise. However, I have yet to see anyone who actually accepts this as a payment alternative so it's a waste of time for me to bother at this time.
I have not used this option. It is not available in my country. Only Paypal support my country. Hence i do not give preference to any other payment processors. I do not want to get into trouble for money transfer.
