S2ML Use Cases Revisited

When the "e-relation" is established this is perfectly OK, but I lack support
in S2ML for the entire "e-relationship" process.  I.e. Requesting a partnership,
potentially being Granted a partnership,  *then* Executing the partnership, and
eventually Terminating the partnership as well.

The use-case is simply scalable e-business with a multitude of partners, where the
relations may be rather short-lived, the interest in performing mutual configurations minimal,
and even trust be relatively limited.  "Normal" business in my opinion.

- Is this really achievable? Yes, it is not even principally hard. Agreeing on details is always hard. 
- Wouldn't this be a major revision? Yes, almost back to square #1.
- Does this have anything to do with challenge-response authentication? Yes, it can't be done without it!
