I've swung to Filter as a concept. We're really discussing the same concept as ServletFilters. Can we model on that? Change the input, block the input, change the output, block the output??
If we're blocking and transforming, then is it just a filter concept? Can we write a FilterCollection and FilterMap that both take filters and delegate down to their internal collection/map?
