Rodney Joffe (who built/ran some of the DMA's opt-out systems for direct 
surface mail marketing) built a prototype of an opt-out system where 
you'd run your list against his, and get back a cleaned one (this can in 
effect be reverse mined).  He built this specifically to prod the DMA 
into moving forward on one of their own (or use his).  When the DMA 
finally announced they were going to build one, Rodney dumped his.
Rodney's had the obviously necessary feature of "domain-wide" opt-out - 
why _shouldn't_ a corporate domain be able to opt out?
Rodney's list immediately showed why no-one will ever accept a global 
opt-out list:  within a week, domains comprising on the order of 60 
million email address had opted out.
