When the advantages are seen the market will take it up, with normally a few early adopters creating new businesses.

AFAICT Banks and Merchants are gearing up for mobile payments which are based on "Apps" rather than on browsers and for the purpose suitable (non-existing) W3C standards.  This is similar to authentication where the trend is clear: Leaving the Web for "Apps".

I envision a web of wallets, a user may have many wallets all talking to each other and triggering things.  Your fridge may order food on your behalf when it gets low.  A family may have a shared area for photos and video, with payments triggered as more files are uploaded.  A person may track their work locally for analysis, then send a summary to employers and accountants etc.

I like the wallet metaphor in this context.  It's not hard to create and destroy wallets spontaneously, to add block chain technology over the web, to deploy smart contracts in javascript and to have personal coinbases (aka currency mints) regulated via a ripple-like web of trust.

I see a distinction between wallets and the things they contain. Joerg Heuer provided a nice list of the different kinds of things that a wallet could contain. When it comes to synchronising a pair of wallets, an object oriented approach seems reasonable, where objects define and own their properties and methods. The wallet can merge its contents, but when it comes to merging payment instruments of the same kind, then this is something that the payment instrument should be responsible for handling, including resolving any conflicts that may occur.

You have a bank account which you'll periodically put money into.  You may have a digital wallet too.  What coins you put in your pocket doesnt matter, in fact you can put anything in your pocket.  The wallet software handles these cases (and I think should handle these cases) interchangeably. It's a case of giving the wallet a URI then key value pairs like an object, then what I do is add hooks when a payment is made, or have daemon processes making payments, or triggers when a smart contract is fulfilled the payment is made.

Some of this may probably be suitable for v2.0 of the web payments spec. But I probably will have it all coded up and working in an MVP by the time v1.0 is out.
