You wouldn't have an example you could share, do you? :-)

The client gets all the initial EOs that are "visible" in the scroll-view area of the window when it is first displayed, and as the user scrolls or makes the window larger, the client-side app automatically requests additional data from the server-side app depending on what was now "visible" in the client-side window. This made for a very quick initial load, but "required" a fast connection to then server to make it smooth.

Not sure how you would deal with that efficiently with a HTML client… maybe with a little choco-hazelnut goodness?
