The main platform I have to work on is Windows, and I had seen that
before but disregarded it since it had no Windows support.  However, I
just checked, it looks like Windows support was *just* added (version
1.3.3, the current version, 1.3.4 is in progress), fascinating.
Still, a completely in-boost option would allow for all the template
magic everyone here knows, thus it could become higher performant then
any other MPI library out.  Possible incentive anyway.  :)

What about expat though, why not use something built-in?
