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 selection, and saved it back to disk.

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.

Nevertheless, you can easily in your app implement a variant of optimistic locking: when saving, check whether the contents on disk had changed from the time you loaded the file in or not (using eg. a MD5 sig, which is easily obtainable via CLI utilities -- man md5). If it has, issue a warning.
