Have you thought about using the logdata from caching proxy's to check
against this data and the other SURBL lists?  The caching proxy's
logfiles contain a very good view on which domains are used while surfing.  
While not all domains that are used are legit, I would be
surprised if active spam domains were frequently visited over a period
in the past.  Those frequently surfed to domains shouldn't be
whitelisted by default,  but it could be a trigger to have a closer
look before placing them on a list.

A very nice thing about this data is that it has a long period of
usefulness even data from a few months ago will be very usefull, if
not more usefull than the data of today or from the past week.

A caching proxy could also make good use from the surbl lists.  Not
caching spammers domains or even adding a delay of several seconds (or
even adding a warning page) before returning the page could be
usefull.  Especially in non ISP use (organisations, companies,etc...)
where there are less problems with blocking content.
