Hello Cal, Sorry for the long delay in replying to your message. Please see my reply to Nick's related post (today) where I mention the possibility of using image operators from the jai-tools project (http://code.google.com/p/jai-tools/)
In particular, I think you could accomplish what you want to do using the ZonalStats operator with a JAI ROIShape object to represent your clipping polygon. The ZonalStats operator was being ported to GeoTools (see the unsupported/jai-tools module in svn) by Simone and Daniele. I don't know if it's usable yet but, if not, you could use the ZonalStats operator from jai-tools directly on the backing image of a grid coverage. If you try this approach please let us know how you go.
