Re : "downloading the internet". I personally write interactive pages, in PHP, and the page is only created on a request, and it entirely depends on what that request is. For example, I have a fantasy football site which allows users to compare any number of player's performance in a graph, which is generated dynamically. To get all the results would be impossible. Also, the jpeg (or was it a png, probably png) graph is itself generated directly from user input, thus can't be replicated without the same inputs. Dynamic content is what the web is becoming, static pages don't exist any more.
