Okay, since the googledoc kept crashing, I have taken all the previously mentioned comments and put them here! Keep discussion to this post now please.
I have a somewhat better gauge of who is interested in this, so I'm updating the post with 1. a more concrete timeline! And 2. Some other stuff I'm going to need. This is all drafty and I'd like very much to work with people to make this epic and not a total clusterfuck.
