I know that SV will have a more limited audience (thus my comment about 
the high barrier to entry). But I wanted to be sure that people were 
aware of it. I'm hoping one day to set up some sort of distributed share 
of the blacklist information though. This would allow a separate plugin 
to utilize the information, though without the firewalling abilities.

Since SV only blacklists a host after it triggers spam tests multiple 
times, I consider it to be fairly high-confidence information. And since 
it automatically expires entries after a period of inactivity, it 
shouldn't have too many false-positives due to dynamic IP addressing.
