I must disagree -- in many cases some form of dynamic pages is quick, cheap,
easy and convenient; often far more so that cobbling up some java applet. 
Yes, it introduces a bit of complexity in caching and refresh behavior, but it's
nothing that can't be dealt with by a little bit of good design (and by adhering
to a few simple specs).
