That would be slick but you would still have the problem of deciding how to batch up your results without actually retrieving the full set. You still need to determine how many rows you want to display and how many pages. Are you thinking of using something like a keyset cursor? Something similar could be implemented using the standard DAO/VO pattern. I've heard this described as ghost objects. The first data retrieval only returns the primary keys populating ghost objects. The set of keys are used to retrieve the details/rest of the object per page. Your initial inquiry returns the full set of keys matching the criteria.
