It would be nice for those of us with fast connections and if the PC servers could handle it gracefully.

If we do get that feature, I hope those of us who can't cope with it will be able to switch it off. As I've mentioned elsewhere, I use a dialup connection and wouldn't want to wait five minutes for a page to download. Even when I've been really interested in a long file such as a video clip and been willing to wait half an hour for it to download, my browser has sometimes bogged down partway through.
