thanks for the quick response.

i've never used Boost before, so need to understand some of its basics.

but as soon as i get this working, ill will contribute my own case as an example for sure.

no

Feel free to contribute one.

If I had nothing else to do, I would

a) make a stream_buf which uses MPI
b) use binary_iarchive and binary_oarchive with this new stream_buf
c) open one program with binary_oarchive and the other with binary_iarchive
d) do ar << on one end and ar >> at the other
e) stand back and let'er rip.

--> so this way it would be possible to mix plain MPi with Boost::Serialize right?

thanks
