TinyMailto offers a unique approach to spam proof your email address.
The free service first converts your email address into a standard webpage address. If a real human being (and not a email address harvesting spider) clicks on that email webpage, he will have to solve a CAPTCHA do know your email address.

Good idea and a nead implementation. But if the tinymailto service is down, there's no alternate route for site visitors to retrieve your email address.
