A quick way to do this would be the directory_watcher gem. It watches  
files in a directory and notifies you when those files change -- add,  
modified, deleted. There is a fourth file notification event called  
"stable" -- this is sent when the file has remained un-modified for X  
amount of time.

It's all ruby code, so it should work on Windows and Unix equally well.
