+1 to= the idea of recurring payment requests.

Perhaps one way to realize this would be to add an optional URL to the Paym= entRequest object where the next PaymentRequest can be fetched and the date= at which the merchant expects the next payment.

Hi,

I would li= ke to propose an extension to the Payment Protocol (bip-0070) to address th= e case of recurring payments in Bitcoin -- new bip or modification of=A0bip= -0070.

There has been a lot of growth in the last few years in= the 'subscription economy' with many new companies embracing that = model -- online video, gaming, groceries, newspapers,... In parallel, Bitco= in is growing into a mainstream currency (hence=A0bip-0070), and so the nex= t logical step would be to define a protocol to address that need.

We have been working in the past few years on an open-s= ource billing platform (http://kill-bill.org/), and recently came with a prototype to do recur= ring billing in Bitcoin (see=A0http://thekillbillstory.= wordpress.com/2014/01/20/bitcoin-plugin/=A0and=A0http://thekillbillstory.wordpress.com/2014/01/11/coinbase-in= tegration-experiment/).


The work flow would look similar to the = one from bip-0070. There would need to be some additions; the flow could be= summarized as follow:

0. Click: 'Subscribe No= w'
1. Wallet would get =A0a RecurringPaymentRequestAuth which describes t= he nature of the future recurring payments
2. The Customer would = get prompted from the wallet to authorize it.
3. The wallet would= then poll the Merchant server (startup time, and/or well defined frequency= ) and potentially merchant would start issuing a PaymentRequest); the role = of the wallet is to ensure that PaymentRequest is within the bounds of what= was accepted by the customer-- amount, frequency,.. If it is, then it woul= d make the Payment the same way it works for bip-0070

Is that something that the community would be intereste= d in? We could provide more details about the protocol we have in mind (mes= sages and flow), and also provide an implementation with bitcoinj as a wall= et and Kill Bill as a merchant server.

Le me know what you think.
