The only disadvantage I see, is a single point of failure, and a point for concentration of attacks. Marc At 13:14 3/4/03 -0600, you wrote:

Not for nothing, but there's so much time wasted with all these diversified spam systems.
Many of these systems have been shown to falsely flag non-spamming sites, and the more reliable ones unfortunately don't catch a majority of spammers. This leads to a system where administrators (or users) can locally tune preferences for the level of paranoia they wish to suffer from. This would not be possible if there were only one model or provider.
I've been reading about Barry Shein's proposals and I have to say I am on board with a centralized -single- system based on his young, but intelligent, model.
If there were any single, centralized organization I trusted to do my thinking for me, I'd agree. This is also the same problem that PKI faces.
