[discuss] let's get concrete

[DAVID JOHNSON]

At some personal risk, I am going to emulate george and try to pose some concrete questions.

If icann is to continue to perform the dns related iana functions, is that going to be just because they are doing it now, and want it, or because discussing any other option is "out of scope", or because some existing or new entity contacts with them to do it?

If the mandate comes from some counter-party, what are the terms?
(certainly good operation of the iana function. what other conditions?)

If there is such a contract, how would it be enforced? 
What reason would there be to think the counter-party would enforce it?
