I've mused that such a thing might be possible, but I've never  
considered how it should be done or where it would fit into the library.

Yes, I'd like to learn more about this. I don't expect we'd be able  
to support this feature in the initial version of the library (just  
covering MPI 1.1 requires quite a bit of effort, and we've had  
requests for MPI 2.0 features as well), but I think the (candidate)  
Boost.MPI would benefit from the ability to propagate C++ exceptions  
across processors.
