Matt P., Tres: As noted on in a comment another post, we could grab metadata, but don't currently. As Blueberry correctly notes, getting that metadata is a bit messy, as there are many apps in use with Airfoil. For the 3.1, we settled on a standard image and text to send. For the future, we'll consider slurping from other apps.

Grover: Front Row on the Mac Mini has no capacity for receiving audio, I'm afraid. You can do it with Airfoil Speakers though, and once launched, you wouldn't need to drop out of Front Row. Open up Airfoil Speakers, and go to the Preferences. Turn on the Start at Login pref and turn off the Float pref, then close the window.

Now, Airfoil Speakers will always be running (unless you expressly quit it), and the Mac Mini will always be ready to receive audio. It will not receive any visuals, though this is something that could change in a future Airfoil Speakers update.
