Nice solution. (But sites that linked to your pages before rewriting will now have those links not indexed in search engines (minor issue). Also if rewriting was so cool, then it would be the default and one wouldn't need to follow instructions to implement it.) But mainly: those links should have nofollow in their <a> tags. OK, thanks.
