Agaric Wants Registration flow: Let people register or log in while posting content

UPDATE: Someone's gone and done it: Inline Registration

Registration flow, workflow registration, viral registration- call it what you like, just let people register or log in at the same time as they post their first content on a site!

Notes and other approaches

Closest thing out there, finally found, is a 4.7 module called Lazy Registration:

http://drupal.org/project/lazyreg

Ideally register-or-login-while-posting should be combined with ajaxified log in, register, and password reminder forms -- that can pass info back and forth to one another without leaving the page with the content. The password reminder (and non-instant logins) would result in content being quarantined until the e-mail address / password reset is confirmed.

So Lazy Registration looks like the best base. Older notes:

A real jerk on this thread claims this exists, but maybe it is easy, if no content is being posted

We're not alone! People write to us and say they want to start using our sites before the registration wall hits:
