I've been recommending people don't do this, because the overhead of  
understanding OpenID is currently still a big barrier to adoption for  
mainstream users. In my opinion, best practice for embracing OpenID  
is to provide it as an optional alternative to setting a username and  
password, and to use sreg to help pre-populate your site's signup form.

I also don't believe that OpenID should be thought of as an either-or  
proposition - an OpenID is just another credential that can be used  
to sign in to a service (kind of like having multiple passwords in  
case you forget one of them).

zooomr.com forced OpenID instead of regular signups for quite a  
while, but they've now switched back to offering both: http://

http://ma.gnolia.com/ remains my favourite example of a well-designed  
OpenID consumer.

Hope that helps,
