very good point. The example protocol in the architecture document is HTTP.
So our first scenarios must be based on HTTP.

By the way, it seems to me that the current thinking in the pre-draft-01
work is that the OPES processor is always fwding messages to the callout
server. This may not be the case!!

I would like us to consider this scenario.

1. Gold, silver and copper services provided by a service provider
2. Gold package, looks into user prefernces (stored either locally or thru a
URI or whatever)
3. User trust the OPES processor with his financial/private data, willing to
expose some of the preferences to selected companies.
4. User can log on with multiple devices (wireless, PC)
5. User requires language translation (or location based service), that is
conditional on the access device
6. user is willing to pay for translation based on various criteria and
he/she prefers company X.

Now, company X is not willing to implement OCP (OPES Callout Protocol), but
company X provide the translation as a Web Service.

How would the predraft protocol would be used here. Is the OPES provider out
of luck. Here the customer can be a Multimillion dollar company.
