I'm curious about business use. Let's say a photo studio is using Photos with each project as album in the library.  Keep it simple with maybe 4 employees with access.  Their computers are used for both personal AND business use.  As I understand it, once they sever the connection...their personal library on their computer will now swell to include the entire company library as it stands at the time.  Is there a way for the host or employee to limit or prevent this?

And about the quality of originals as the first commenter pointed out...is that somehow preserved somewhere?  I can understand for shared storage detailed "preview" images are what's generally used...but what happens to the originals?
