I've been talking myself blue in the face for some time now trying to convince the never-ending parade of would-be cache builders that busting a gut to be "completely transparent" was simply not worth the effort because i was convinced it would turn out to be a bug and not a feature, especially when people had to troubleshoot problems. but noooooo - The Department of Helping Way Too Much always has room for more headcount. oh well. cheers, -mo "Nature proceeds by performing millions of experiments in parallel.
