Let’s be perfectly clear about this. With FCP and X-SAN, anyone connected to the SAN can open a project, make changes and close it. As Keith says, “Last one to save wins”.
We have almost 100 editors working with shared projects, episodes, media every day. Here’s how we do it.
Editors identy their project with their names, “RW1800MarkR”, and work within that project. They work locally, but save “globally”. At the end of the day, the editor will save the project to their local drive and to the SAN in a “project back up” folder. If another editor needs that project, they will find it, pull it locally, rename it as “RW1800Editdude” then save it both locally and globally. It is this naming scheme that keeps things in order, not FCP or X-SAN.
Also.. keep in mind, that for FCP, the project is less important than the media or the “sequence”. So for sharing projects, we put the sequences only into separate, small projects and zip that around the company.
Hope this helps.
