title: Is Adobe AIR a good choice for building an app usage-monitoring tool?
body: <p>I've been looking for some some answers about Adobe AIR in its current version and I'm wondering if any of you could let me know if I can do all these things with an Adobe AIR app, since I know they have their limitations:</p>
  
  <ul>
  <li><p>Sit in the system tray in Windows and as a small icon in the top-most bar in OS X while running in the background? Will this require different programming to support both platforms?</p></li>
  <li><p>While being in the background, be notified of which app gets the focus and when? Ideally, I would also get the name of the document, URL of the website (if we're on a browser with tabs) that has the focus, etc. I'm trying to build a tool similar to RescueTime, that tells you how much time you spent on each app or website.</p></li>
  <li><p>Have a specific system-wide hotkey (like Alt+Space) that when pressed, the app comes up into focus (from being in the background)?</p></li>
  <li><p>Show notifications (Growl-style unintrusive popups) for specific events?</p></li>
  <li><p>Being notified when the system gets inactive (screensaver pops up, users "sleeps" computer, etc)</p></li>
  </ul>
  
  <p>Thanks! </p>
