   I'm having problems understanding your base argument here. It seems
to be that you are afraid that Boost.MPI will make your prototype
program so much better and easier to write that you won't want to remove
it. Wouldn't this be exactly the reason why keeping it would be good?

   I like and use Boost.MPI. I voted for inclusion during the review in
the Boost developer community. However, what you should do in your
program is use those tools that produce the right trade off between the
best performance, easiest to develop correctly, and most maintainable
program you can. If that means using Boost.MPI, then remember that
questions about it are answered at the Boost Users mailing list. If your
decision is that that does not include Boost.MPI then you will have some
other challenges to face but experience shows that you can still produce
a very high quality program.

   Choose as you see fit, just be sure to understand your own reasons.
