It seems to me that Asio is a general framework for all things async,
with TCP being the only concrete thing implemented right now. Then, unless
MPI has an comparable framework, you cannot implement Asio on top of MPI.
Unless "implement Asio on top of MPI" means "add support for Myrinet in Asio" :-)
