Jed and I previously talked about this offline. I don't think that dynamic windows are a good match for his problem because all that it would do is shift the burden of determining buffer address starting offsets from the MPI implementation to his code.</blockquote>

That seems like something that should be possible without minimal overhead relative to reusing existing memory, but maybe I'm missing some details of the implementation.</div>
