Re: Thanks to all and next steps

The challenge with defining the end is that I think there are more than one
ways to end :)
We will need to define what those are but they could be different for push
and pull payments and whether or not the scheme in use performs some kind
of out-of-band confirmation of payment.

To handle all of these I think we'll end up with two different API methods,
something like "requestPayment" and another for "completePayment".

The payee will call both and the response to complete payment should be the
final signal that the payment is complete.

I don't want to get into too much design detail here as this is the job of
the WG but suffice it to say I expect they will define an interface and
flow that makes sense and caters for all of the use cases in scope (i.e.
both push and pull)
