We've gotten a lot closer in another week. It appears that the Convergence Proposal put written up by Rich Elmore and David McCallie has been able to get general agreement from just about all parties. It includes many of the capabilities that I talked about yesterday in "A way forward", and we also looked at some really good pictures developed by Janet Campbell.
There are some clarifications needed before we make a general call for consensus on the project, and a team has been put together to make those clarifications (I'm on it along with Rich, David and a few other people who have also be "working hard" this week).
My last comments on this are that we need to address requirements of Source HISP and Destination HISP, not just "requirements of the HISP", and that we also need to determine what the existence of an NHIN Direct address implies. Some e-mail addresses in the real world are send-only and don't recieve, and others are recieve only and never send. Is that allowed in NHIN Direct? It seems like it should be.
In any case, I think we are very close, and we'll be able to announce what the NHIN Direct protocol is next week.
