A few things. First, as far as the network activity noticed when using this, your iPod is acting like another computer so you're going to see some kind of activity. LittleSnitch didn't see anything trying to call home and I had my internet connection unplugged, so I'm assuming all is safe on that front. On a different note, this plugin didn't work at all for me. My iPod is home to more than 8000 songs. At the 5 minute mark, the plugin was still not finished taking inventory, and in fact, my iPod had frozen. When I tried to force quit iTunes, it gave me the option, but wouldn't do it. On installing the plugin the Finder and all other applications acted the same way causing me to restart first my iPod then my computer. I didn't think it was the plugin at this point, but after the second time with problems, and after uninstalling the plugin with no more problems, I'm thinking it was the culprit. I think it has great potential, but it's not ready yet.
