I've been more concerned with a separate issue which is attempting to get a better handle on what an otherwise incompetent communicator is trying to say by looking at their previous statements. A lot of people come asking for help here and only give us bits and pieces at a time but if you string together their statements over hours or days the complete picture comes together. For those people I want to do a grep of everything they have said, ever. I sometimes do this.
I've also often used a similar program to http://grenekatz.org/cgi-bin/cbsince to catch up on what was said while I was out for an hour or so (usually because I was interested in what was there when I left). This would be nicer if paged but it was easier to just display everything at once. I don't know what else you were looking for other than displaying less on a single page.
