Good point Chris. I wasn't thinking of clustering (a requirement Jon's...)
I guess that I was thinking that one could do some sort of data thinning and provide those views at smaller scales. Either way, if one thinned the data or applied a clustering algorithm, this would likely be done as a pre-processing step to prepare some data sets to build a WMS on. In short, never mind... Apologies for sending you down the wrong path. David.
