Perhaps not quite as big as you're imagining though. If there's, say, a spamassassin rule for it (we actually wrote one for our initial version of the centmail protocol) then it might be worth your while as a sender to sign up, to help avoid ending up in people's spam folders.
The main thing we're hoping for though, to achieve any kind of critical mass, is that you'll want to sign up initially as a sender simply to promote your favorite cause. Confer the popularity of Causes, the Facebook app.
We certainly don't imagine Centmail as a panacea; but you could imagine it becoming a reliable additional feature for your spam filter.
Think of it like hashcash, but instead of burning money/effort, you send it somewhere useful. Come to think of it, maybe this could be made more palatable by combining the hashcash concept with some seti@home-style distributed computation problem. Look for aliens in order to send email!
