There are a few ways to do it, but none are ideal and we have a proposal pending in which one item is to improve staggered grid support (but we won't hear back for several months). If you want to do this, it would be useful to discuss how to manage staggered grids. The petsc-dev list would be the best place for those discussions.</div>
