v0.14.10, explained here: A first look at Obsidian Shared Vaults (v0.14.10 insiders beta) - YouTube
Posting for others as I was digging through the release notes for a bit and couldn’t find it, turned out it was buried there.
Note to be taken it seems to require active Obsidian Sync subscription from all collaborators.
A takeaway from the video is it’s not really for parallel editing with multiple people at the same time.
… require active Obsidian Sync subscription from all collaborators
bummer 
Not sure if shabegom’s Liveblocks plugin can be a solution for this?
I think it should be possible (with Sychthing for example) for each member of a team to share a read-only folder of their notes. You could not directly edit another’s work, but you could live-comment by linking a note to it, which would show up as a backlink
What about a plugin that copies the markdown into a collaborative online-editor, like Free Collaborative Markdown Editor - onlinemarkdowneditor.dev
after paste, one can simply copy the web-link and share it
(afterwards the plugin could maybe add the link to the note/front-matter?)
Of course this is not something for privacy-aware people, but it’s free! 
I tried to find other free collaborative markdown-editors, but couldn’t find one yet.
Besides this self-hosted solution: New Plugin: Sync to Etherpad Lite for easy web-based collaboration!
Obsidian uses Codemirror under the hood and CM has a collaboration plugin:CodeMirror Collaborative Example
It does require a server though, so the Obsidian team would probably have to implement it instead of it being done as a community plugin.
I wouldn’t mind if it were a plugin. But I haven’t seen any collaboration plugin yet
a collaboration plugin or feature purchase, a-la sync or publish would be great. allow teams to take notes as a unit during a meeting or update a shared file throughout the day to address larger concerns. lot of use case here.
Have a look at Peerdraft! Recent updates allow it to do a lot of what you’re looking for!
This is great! would, I think obviously, prefer to have the payments and management be under one line item but peerdraft seems like a great solution in the short term.
I waited for three years for something like Peerdraft to come along, and I tried everything for using Obsidian for collaboration. We the developer first launched it, it was only peer-to-peer, and you could collaborate only as long as you had the connection open. I approached him about the possibility of developing it further, and he’s been super-responsive. He’s an indie developer, and he’s got some real costs to recoup, but I think it’s very much worth supporting. I’ll be doing a workshop on using it, as part of Nick Milo’s “Linking Your Thinking” course, and I hope I get a chance to write up some of my workflow soon.
I’m surprised this hasn’t been posted already:
Can close the thread now.
<3 thanks @AlanG
Matt, one of the Relay creators here. Yep Relay does live team collaborative editing, is built on Yjs, lets you share folders within your vault. Here’s a video tour:
We’re a team of two (me and Dan) and we’d love your feedback and support.
And PeerDraft and developer Dominik are great too!
Wanted to chime in and also link screen.garden, which allows for realtime multiplayer collaboration without merge conflicts, folder/vault sharing, image/general file sync, and lots more fun features
honk has gone silent.
Really looking forward to this
