First off, I love Airplay and the ability to have my music "follow" me around the house. But here's one issue. Let's say I've got: 1. An ATV2 in the basement 2. An Airport Express in the living room 3. My MBP with speakers in the den. I can Airplay music from my iPad to speakers connected to the ATV2 or the Airport Express. But...I cannot push music from the iPad back to my MBP with connected speakers. Sometimes I'll have Pandora streaming on the iPad and I'd like to push it to speakers connected to the MBP, when I'm not using my computer. Anybody else run into this issue?
