But I believe that's not the way the economics works.  There really is
no such thing as a "different kind" of captcha at this point (I think
audio <dave_barry>or even video for lip readers</dave_barry> can
continue to weed out all but the NSA for a while yet), but breaking
CAPTCHAs can be done with COTS now.  (Here the "C" stands for "common"
not "commercial".)  So the only question is when will a reasonably
powerful script become available to all wiki spammer wannabes.
