Might be interesting to contact the CBL people that provide most of the XBL 
data and see if they would be interested in setting something up that would 
parse out the url domains directly in the scripts already running on the 
CBL spamtraps.

There would still be a need for further processing to eliminate FPs of 
course, but a feed at the source level would mean a substantial reduction 
in the time to listing as well as a larger data set.
