This might be wise to do at the same time when we calculate the hash number for the file contents.

Hmmmm, in my case that would mean scanning through roughly 6 gigs of mp3 files. Of course you don't have to decode all of that data but just rushing through it still needs a bit of time. Maybe a few minutes or so. And since it's an IO intensive operation, you will notice your computer almost come grinding to a halt.
But not everyone shares as many mp3s as I do, but some share even more. Maybe doing that scanning in a background low-priority task could be a workable solution...
