I have a plugin which is a fancy Membership Management system, named Magic Members. They use a captcha, which I kind of hate, as I imagine most people on the planet do. I'd much prefer to use your "WP No-Bot Question" process, which works fine with the standard WP registration page, but ... for the Magic Members registration page, I might need a custom installation. Would you be willing to coordinate with them to get your plug-in to be Magic Members friendly? If I need to pay a technical support fee or make a donation, that might be fine. I would just really prefer to use your method to stop the bots.
