Hey Frans,
Was wondering if you will (or already are) using the new features of SQL 2005 (ROW_NUMBER) for paging. Maybe there's no real advantage to doing it the "new" way--I haven't seen any performance tests yet.
As a semi-related aside, I'm currently doing a project in which I can't use LLBL, and having to support paging via stored procs. It's not that bad until you realize how hard it is to support dynamic sorting within a proc.
The ease of using typed lists with paging/sorting via LLBL is worth the cost of the product all by itself.
