I've plugged this collaboration project a few times recently, and have no relationship to it other than discovering it (via YJS' "who is using" list[1]) and finding it fascinating:

What I find most interesting about it is that it has reduced the state of multiple 'smart' user-facing widgets/apps into a common, lowest-common-denominator format (a text document) that lends itself more easily and intuitively to collaborative editing and CRDT operations.

I don't know for sure whether this is the path forward for CRDT-based applications in general, but I think there are valuable ideas there. It does raise the possibility of the widgets/applications occasionally being in 'invalid' states; but rarely in a way that the human participants wouldn't notice or be able to fix themselves.

Whether that scales to the complexity of the state management for a multi-track audio editing session, I don't know; but it could be instructional to compare.
