FYI, you can now use email addresses as OpenIDs by implementing the Email Address to URL Transform protocol (http://eaut.org) and backing with with emailtoid.net. I definitely would like to be able to use an existing verified identity than having to create yet another account.
I second Toby's suggestion to use OAuth -- a much more lightweight (and thus more likely to be implemented by other web service providers) protocol. It's also designed to complement OpenID, which is being discussed here: http://uservoice.uservoice.com/pages/general/suggestions/55
