What would you suggest? Would it be like Valheim (any many other games) where if you want to collaborate, one person needs to be the host and run their copy of the app and if they aren't running it no one can work?

Or are you suggesting the average user would some how spin up a server and run some software and maintain that server so that all the collaborators can access the thing 24/7?

Me, I love that from any of my 7 machines I can access my docs, spreadsheets, tax info, etc. If I have to use a native app then I can only access it on machines that have that app installed. The app might not even exist on some of the machines I use but a web browser does.
