Just to add - Since I implemented this here, and removed all of the other spam protection methods, I've not got a single spam message through, not even in the moderation queue.
This is because if the author/email are empty, then wp-comments-post.php just die(); Because all the spam scripts are made to work for $_POST['author'], changing that alone cuts out almost all spam.

Wouldn't it be pretty easy to make a plugin for this? Have it generate a new random string every time the page loads..maybe not, because wp-comments-post is static. But you could pull off an option query...o god maybe i should just shutup. The more I think about it the dumber it sounds :)

Nope, a plugin is impossible... As for making it random, you'd need a hidden <input> to pass it on, which spam bots could read, so no.
