I have to wonder, if a DNSBL were being operated entirely on a free 
basis (rather than a freemium model), might it not be better to take 
advantage of the large caches out there rather than having thousands of 
individual servers performing the same mundane set of lookups individually?

Obviously this negates the DNSBL's ability to try and pull cash out of 
the larger entities, but purely from a resource management point of 
view, if someone wants to offer a front-line cache for free, surely that 
should reduce load.
