My personal feeling on this is that if you can *reduce* the number of
bytes going over the wire using AJAX, go for it (assuming your
audience can handle it, etc.).  If you increase the number of bytes
going over the wire, it may not be worth it.  In some cases, the
enhanced user experience might make up for it, but you'd definitely
need to do your homework first.
