The key difference from blacklists is that blacklists do not ask ISPs 
whether they want to be listed. Here, the sender actively goes to a 
provider and signs up, and then indicates his accredidation in some 
protocol.

My issue with this is something else - if all of this becomes prevalent 
enough, aren't we essentially raising a barrier of entry for new domains 
on the Internet? Doesn't such accredidation service essentially become a 
gatekeeper for the Internet?

Yes, I read Microsoft's proposals about different types of tricks for 
different domains, for example hash cash-type puzzles for smaller 
domains in lieu of accreditation. I am still not convinced that a given 
ISP will bother with supporting both accreditation and hash cash, they 
just might take the easy way out and only support accreditation services.
