Gravatars without email all end up looking generic

When your blog has this option turned on
"Comment author must fill out name and e-mail"
and multiple users leave comments, if these users do not provide email addresses it will appear that they are all the same user as the identicon/monsterid/etc icons will be the same.
With two additional lines of code, you can substitute the IP address in place of the email to get a unique hash in order to distinguish one anonymous/non-emailed user from another.
