Has anyone seen a site claiming to use OpenID but actually phishing with a redirect to a similar-looking URL (e.g. typo-domains of google/yahoo/etc.) to grab your password? I always check the URL before entering my credentials, but there's always the risk of similar looking glyphs at a different code point (is Unicode allowed in domain names yet?), or just typo-blindness.
