Is there an app to use the Wake On Demand Feature from remotely from outside the home network? I've seen a bunch of Wake On Lan apps, but I need to do this while I'm out and about from my iP4. I have a Mac Mini connected via wifi to an AEBS's 5ghz network and I'd like to wake the computer while I'm at work. Paid's OK but Free is better. I don't need any features other that waking the computer. Thanks!
