Here are some unasked for comments :-)

In that case, yes, clearly.  I agree about the careful thought.

>4. What should the name of the new module be.  We had discussed not

I fully agree.  MPI3?

>5. Review what integer kind should be used for things like tags.   
>We've previously decided to use default integer kinds except for  
>possibly for counts, in which case we would specify a specific kind,  

Are there any tokens representing opaque types left?  Other than counts,
those are the only ones that I can think of a strong reason for adding
the complication of a special KIND.
