Airplay's pretty great, right? You can zap whatever music you like on over to your compatible device. Fun. Great. Just one problem: Only one person can be AirPlayin' at any given time. Minor quibble? Maybe, but it's a tad antisocial.
Think about it: Your friend wants to show off his knowledge of the Greenpoint IndyFolk scene by playing a song over your Wi-Fi-savvy device. No problem. Until you want to one-up him by playing something else—he's got to hand the connection over.
One more reason to wish we were rich enough to own the fabulous $600 iPod dock that is theB&W Zeppelin Air:: Starting today, it has a special app that lets multiple people jump on its AirPlay feed at the same time. It's kind of like a closed-circuit turntable.fm, allowing anyone who has the app to hop on the airwaves and play songs from their iOS device's music library. And whoever starts the session has veto power.
