There are classes for wrapping sockets in an iostream
available on the internet (e.g., socket++ and skstream
turned up in a Google search).  I didn't find anything
similar for MPI (not that I looked very hard).  If
nothing else you could emulate a socket connection in
MPI and use the socket wrapper.
