Would be really neat to put Drawpile on the Fluid Framework. You could easily map Drawpile's ordered operations into distributed data structures. I did a similar thing a few months ago with QuillJS's operations and it worked great!

The main advantage of that integration would be a ready made Azure service + future integration with Microsoft Office.

Interesting that there isn't any mention or use of CRDTs, that would have been the first thing to see from this document.

Nevertheless, it is still refreshing to see a different way of doing things like collaborative drawing without them.

Curious to know of this design decision.

Drawpile solves the second problem in the most simple way possible: all edits go through a central server, which distributes them to all connected clients (including the originator) in the same order. So, when a client receives commands from the server, it knows all the other clients also received, or will receive, them in the same order.

You don't need CRDTs if you have a centralized server and require clients to be connected to make edits. CRDTs are useful when you want to enable collaboration in a decentralized way.

So does this mean Figma is decentralized since they are also using CRDTs?
