This looks awesome Raul. I have to frequently rsync certain application 
data between my two machines, and with something like this I could only 
fire syncing when the important files change.

Great find.

Do you know if there's a tool already written with this that would watch 
a list of files and execute a command when a given notification was 
received? It wouldn't be too hard to whip something up, but I'm sure it 
already exists.
