Our feedback widget from http://featurelist.org http://featurelist.org doesn't require any login and the email is optional. It's modeled after the same sort of side-widget you see on a lot of YC sites. The idea is to get the user feedback as quickly as possible before they get tired and their good will is drained. We liked this so much we made a service for this that we use on all of our sites (and is free for you to use on your sites, too). That feedback is private and can be promoted as either an upvote or a new public feature request by a member of your team. For users to leave a public feature request on a project themselves, they do have to create an account. But that process is like Reddit in that you create it just with a name and a password without having to provide anything else (email is optional).
