icopulate is a new tool for ipod fans:

Now your iPod® can get some action and do direct data transfers at the same time! Here's how it works. Simply apply a dab of the included iLube© onto the dock connector of your iPod® and slip it into one end of the iCopulate's™ latex sleeve. Find another consenting iPod® in the vicinity and deftly insert it into the opposite end of the sleeve.

Once the two iPods® are joined the real fun begins. Using the easy to navigate menu system of your iCopulate™, you can transfer music from one iPod® to the other; single tracks, albums, all songs, or even whole playlists. Since the iCopulate™ uses the dock connector for fast file transfers you can transfer several dozen tracks in less than 30 seconds. Now that's a quickie you can write home to mom about!
