Yeah, that partly was what I was trying to get at, but I was also thinking that the collaboration system behind zeroth posts could be added to other areas in the site. Like, if we had the ability to collab with one or more people in the test thread, it would completely erase the need for google docs/pad/etc. for collab posts.
The main question when it comes to collaborative features like this is access control. I could pretty easily make a section of the site completely collaborative and allow any account at all able to access and edit what's on it. But you also run the risk of trolls coming by and wiping/defacing posts.
To defeat that, I could also add the collaborative revision system that currently exists on 0th posts (check out any thread with a 0-post you're able to access and click the revisions button on the top left, or get a perma-link to a post you created and add '/revisions' to the end of the URL). That would allow any person to revert the thread pretty easily and see who defaced it. It would also allow trolls to be caught and prevent your information from being lost. The only issue would be if people who don't know the feature exists end up thinking that they just lost everything—that'd be really unfortunate (along with any deletion wars that might pop up).
The most robust solution, true access control, would involve the thread creator adding verified editors to a post/thread like Co-GMs. That feature would more than likely require a change to the database (unless I did a hacky solution that may or may not work), increasing the amount of time it would take to implement.
That being said, I'd like to hear all of your thoughts and suggestions, along with what you'd like to see out of that kind of system. I can always throw the changes onto my experimental GitHub branch, so I can try mocking something up and seeing what it looks like. Let me know what you think ^_^
