The system you have described is very similar to ones that have
been described and implemented in the past. Personally, I agree with you
that this particular method of fighting spam is likely to form part of a
very effective anti-spam system. The most interesting feature of such a
system is that it has immediate benefit to someone who adopts it and it
can be adopted by individuals rather than requiring support from ISPs,
network maintainers, etc.

Is there a need for these systems to be interopable as per Eric William's
requirement spec? Will someone have to eventually define a protocol so
different "opt-in" systems can talk to each other?
