Just ran across Stormpath [1] in a recent mailing [2]. They provide a
hosted user management service instead of you having write one (using
Devise and CanCan, for example). Has anyone used them or anything like
them? What do you think about off-loading your app’s authentication and
authorisation to a third party?
