Scrivener for Joint Projects?

Is Scrivener suitable for shared projects?

I have seen in the forums somewhere that it is unwise to create a Scrivener project on a shared disk, and access it from two different instances.

Can a project be shared between two people using the sync via dropbox feature?

I guess dividing the work into scenes will lower the possibility of both trying to edit the same file at once, but would there be a possibility of losing work?

Yes, accessing Scrivener from a shared disk via two different users simultaneously is a no-no, bound to befuddle the software.

The way I’ve collaborated is via Dropbox, by saving a zipped back-up of the project which can then be opened on a second computer. But it’s worth reading this thread on Dropbox precautions first, especially the most recent posts.
