new name for Image_CAPTCHA

Hi devs, as most of you are probably aware of, I proposed Image_CAPTCHA some weeks ago. In the meantime, Toby (Schlitt) came up with the idea to make the package a bit more general and to implement a driver concept to support image CAPTCHAs, ASCII captchas and maybe Audio CAPTCHAs. However, in that case, Image_CAPTCHA does not seem to be a suitable name any longer. So before creating a new proposal, I'd like to get opinions which name to choose for the new concept. Maybe as an own "CAPTCHA" package within "Tools and Utilities", or "Text_CAPTCHA" (since it's a text that has to be found out); however I am not too happy yet with either of these two names. Any suggestions? Thanks! Christian
