Radically scaling bandwidth and interface refactoring make strange bedfellows.
For example, one interesting design problem that's presented when dealing with critically accessed pages (i.e. Google's search results page) is tradeoff. Meaning: An interface feature that could add weight to the page could place significant stress on overall bandwidth and server resources owing to the large number of downloads.
For fun, I just wanted to see if I could achieve a balance between the addition of event-based-feedback and Fitts'-Law improvements and the resultant total character weight. I found, surprisingly, that I could make some changes and actually lighten Google's current search results page.
