For cleanup purposes you could implement an event listener that: 1) when a file is deleted looks for a ._meta file and removes it 2) when a file is moved looks for a ._meta file and moves it
For hiding the files from other clients, maybe some sort of filter that hides the ._meta files based on User Agent? -James PS: Ignore my previous reply. I'm catching up on email and going the wrong direction, I think :).
