Like some setting to pick the connection pool from some other existing store for example. To be honest, I have been itching to add to GeoServer connection pool as first class catalog objects that can then be passed around to various stores, but never got around to do it. > It would also be nice to utilize the apis in coverage for serving up > multiple coverages from a single reader.

If memory serves me right, ResourcePool wraps the readers with a renaming class that gives the rest of the code the illusion there is a single raster in the reader.
