I tried out a tip recently for controlling a Mac via Mobile Safari on your iPhone, and it got me thinking, which is often dangerous. I put together this little web app today as a proof of concept (that got a little out of hand). It basically provides a full interface for volume control, application starting and stopping and many iTunes functions, including volume and EQ. All features provide interface feedback and update you with current info from your Mac.
