Doesn't help recover the last 2 hours of work you did because some
editor (person) decided to open your project file, changed a saved

Of course I am thinking of 100+ megabyte photoshop files being served
off a server via gigabit.

It'd be best to issue a warning *before* you start editing, not after.
