Orb's Curt Van Inwegen explains how his company's software allows you to access your music collection on your home PC from anywhere in the world. All that's required is a connected web browser or a connected device that plays audio and Orb's service. What this means is that instead of having to carry your collection of tunes on an iPod or as a batch of CDs, you store them all on your home music server and leave them there. If you are at a pal's house and want them to hear that tune you are describing, you can use your pal's computer to call it up and play it on his system. Seems like the obvious step beyond using an iPod to carry your collection around.
