It's very tricky to scale, and to maintain consistent privileges. NFSv4 map somewhat, but not *perfectly* to CIFS credentials. And lock files become an adventure, because clients *cannot* be entirely in sync with a centralized server, the constant monitoring and updating to be in tight4er and tighter sync themselves cost bandwidth and CPU. So collaboration working with the same files can require thoughtful programming to ensure atomic operation. I don't recommend it: I'd generally recommend picking one protocol or the other and using it everywhere. It's extraordinarily difficult to predict incompatibilities someone may run into with ocmmercial software, written to use lock files with *very* peculiar behavior. And of course there is the filesystem namespace collission issue. In NFS, README.md" is a different file from README.MD or readme.md, and resolving this with CIFS clients o the same workspace can be an adventure. There are many inexpensive office grade petabyte storage servers which rely on Samba internally and would probably serve your needs.
