Need a quick and easy way to get files from one iPod to another? The miShare, which will cost roughly $100 if/when produced, aims to provide the solution. The device works by connecting two iPods to the docks on each end. A specialized Linux OS uses open source tools to access the iPods as mass storage devices, and can transfer music, video, or pictures. When in music mode, the most recently played song or everything in the On-the-Go playlist can be transferred automatically. The alternative of course is to simply buy a DAP that is natively a UMS device, such as a Cowon, which can transfer whatever you want to whomever you want.
