The miShare iPod Transfer System is a hardware P2P file sharing device. Plug a couple of iPods into either end of the thing and presto, you’ll be able to move your music, photos or other goodies from one to the other in the blink of a lawyer’s curse. It’s USB 2.0 so transfers are suitably fast (10 seconds a song they say) and it works with most types of iPod out there. $99.50.
Our miShare iPod Transfer System makes sharing files between iPods easy. Simply attach 2 iPods, slide the setting to music, video, or photo, and start transferring. Share music, family videos, or podcasts with friends and family members.
Not sure why you would need hardware to do this but looks cool. I use iPodRip to do an iPod Transfer.
