I'm not terribly familiar with OOMPI but my brief look-see
got me interested in the ports feature. Something like this
on top of Boost.MPI would be great. Even better would be a
communication interface that could work with various underlying
technologies (MPI, Boost.asio, Boost.interprocess, etc.).

I don't know how practically realizable it is to do with while
maintaining performance, though.

A while back I did some experiments with a colleague to hack
up a UPC compiler to recognize UPC constructs in C++. It turns
out that one can do a bunch of nifty things with template
metaprogramming in the context of parallel computation in the
style of UPC. I wonder if it would be possible to emulate
something like a UPC++ with creative operator overloading, a
parallel communication library and template metaprogramming
wizardry? I don't think it would be possible to approach the
speed of a native UPC++ but it might be interesting for some
machine architectures such as clusters or other low-bandwidth
