I think I have to agree with Terry.
I love to inspire and see new, original, and unintended uses for Open
MPI. But our primary focus must remain to create, maintain, and
continue to deliver a high performance MPI implementation.
We have a long history of adding "small" things to Open MPI that are
useful to 3rd parties because it helps them, helps further Open MPI
adoption/usefulness, and wasn't difficult for us to do ("small" can
have varying definitions). I'm in favor of such things, as long as we
maintain a policy of "in cases of conflict, OMPI/high performance MPI
