James M Snell mentioned his Apache Project... It would be *very* nice if you could see your way to implementing "RFC3229+feed"[1] support in your implementation. As I think you know, the use of this mechanism results in massive reductions in the bandwidth and client-side processing required in fetching updates to Atom feeds. Also, Microsoft will be supporting RFC3229+feed in their browsers[2], thus, we can anticipate that support for fetching delta-feeds will soon be considered expected. The only "issue" with Apache is that Apache *still* does not support the "226" response code...
