Idea: Syncing Wirelessly

I have an idea for apple to further improve the iPod touch/Mac computer syncing system. I'm pretty sure this is possible. They should make the iPod touch be able to sync to your iTunes wirelessly. If you are within say 10 feet of your computer, you could press a "sync" button on your iPod touch and it would sync via your wi-fi so that everything will transfer without having to plug it in.
