Multiwork like...

so i came with an idea, i dont know if can be real in technical manners cause it can be too dificult. but what if 2 or more peope could work on one project at the same time. so lets say i will like to make some plant so, one person will start makind pot and other som plant. this will happend life and both persons will see it and they will be able to edit it together. i think it will help maybe to make more efficient workflow but also more fun for newcomers.
