That'll work fine. Be sure to use the atomic mode, which is safer in 
the case where another user is accessing the old file (it moves the 
old file aside instead of overwriting it in place.)

Saving to a network volume is mostly the same as a local filesystem. 
It's when you get to issues like file locking and permissions that 
there can be differences.

I don't see how this relates to Photoshop, though. It's a Carbon app 
and uses a different set of APIs for saving. It might also be using 
optimizations/tricks such as incrementally updating portions of the 
file.
