I was interested in adding Folder Watching to iTunesDSM so that you could basically have it run at startup and then just automatically add songs to iTunes as new songs were added to the directory. I thought I found a way to do this too here but then I realized you need to run java 1.7/jdk 7 which is still in early release. I then though about implementing my own file watching thread thingy, but that's not really a good idea either as continuing walking the entire file tree every 15 secs is taxing to the system. I could set it up to scan every half an hour or something but even then, it would take a lot of resources. I'll consider it though.
