Change the "would" into "is": it is possible to mix Boost.MPI with Boost.Serialization. Any objext that can be serialized can be sent by Boost.MPI. This was actually the basic idea behind Boost.MPI, to use Boost.Serialization to pack and unpack MPI buffers, or to create custom MPI datatypes.
On thing that I never understood is why you need MPI data types at all. If one is serializing (packing) to a binary array, and sending that, what hae MPI data types have to do with it. If one were using heterogenious machines, I could understand the usage of MPI types. But as I understand it, the MPI serialization presumes that the machines are binary compatible. So I'm just not seeing this. Robert Ramey
