I don't know if you ever used the music service Lala back before it got bought by Apple and shut down, but they had a really nice infinite scroll implementation.
When viewing your music library, the scroll bar grabber would be the correct size for how many items were in your library so grabbing it and scrolling would work right. It didn't load all X number of items you had at a time though either.
