It seems we should provide a DMSDA that is built specifically for staggered grids, with the correct number of "slots" in the correct "locations", it would have appropriate grid hierarchies and interpolation/restriction. Not terribly hard but a bit of basic plumbing code. I would rather have this then try to "tack on" the current DA a bunch more stuff.</blockquote>
