How about useful captchas? http://www.networkworld.com/community/?q=node/15522 I don't know if it is in use anywhere yet, but you use two captcha boxes. One is a control you know what the word is (like we use now), and the other is an unknown word that is trying to be digitized from a scanned book for example. I guess that doesn't address the readability or security though.
I must admit that I hate captchas, but was actually pleased to see one of those captchas the first time I got one.
And it'd dovetail nicely with WMF's mission!
