It's true that the data for this file doesn't change that often. However 
one of the things I'm trying to do is get some kind of coordinated 
information structure created to maintain informational lists that can 
be used for spam filtering. And not just be SA but also Exim rules and 
other software. Sort of along the idea of URIBL information. One thing I 
have ad would like to see expanded is my white list of domain names that 
you can rely on as always good if the FCrDNS matches.
