Ok. This really helps. As you can see, my understanding about what's
going on with Open MPI needs refining. I wasn't sure if the MPI world in
general was moving towards Open MPI as being the one-and-only MPI, or if
this was a parallel development (no pun intended).

So I need to mull all this over some more.

My hope is that the MPI Forum folks will come out with a stand-alone MPI
spec that doesn't rely on any previous versions.

I did have a meeting with our local DITA expert here at Sun, and I'm now
re-thinking this as a possible publication environment. It's too early
in the development of DITA for us to rely on, and truly usable tools are
not quite there yet.

My next stop is to look at what the folks at OpenSolaris.org are using
and report back.

More later. Thanks.
