I talked to an Adobe rep at an event last year and expressed my interest in an intra-office version of Anywhere that allowed for project collaboration between multiple editors. He acknowledged that they were aware of this as a feature people were interested in but that’s about it. I have high hopes for Adobe at NAB, especially with larger and larger projects happening this more advanced collaboration would be super helpful.
To come closer to actually answering your question, we have multiple machines connected to an XRaid stack via fibre, but the PPro software limitations result in having to duplicate project files as to avoid opening and saving while someone else is working and potentially corrupting a file. Transferring sequences is also cumbersome, as you get duplicates of all clips in the project even if you are already connected to the media. If you aren’t using that media that’s fine, but if you already have it in the project it would be nice to be able to disable creating duplicate clips.
Overall it works ok, you just have to be careful when people are working at the same time.
