It sounds like you are interested in something more along the lines of batches of data and not a realtime API.
Banks / Credit Unions / FIs do this now to send transactions between their own networks. I'm not aware of a consumer-oriented version of this, but that's not to say it shouldn't exist. PayPal is starting to move that direction with their x.com API. But you are going to be hit with more charges routing through PayPal than you would otherwise.
