i2i Allows Music Sharing, Legally

As you may not know, I am attending CES 2008 in Las Vegas this year. I am reporting on some of the latest and greatest in gadgetry, and I could have chosen any one of a thousand companies to post about today.
I decided to post on the i2i Stream, because I think it is a very useful product. They just started this year, but they have something that everyone needs: a way to transmit music from one portable media player to another.
All you have to do is plug in the transmitter and receiver to the PMPs. Turn them both on, and the receiver will hear anything that the transmitter is broadcasting. Sounds simple, like something someone should have invented a long time ago. You may say that the Zune can do the same thing, but i2i Stream allows capability between an iPod and Zune.
I don't believe that I have a price on this, but I think it's worth checking out, especially if you are the type that likes to share music with your friends.
