Just to add, there is no NCAA official march maddness on demand app for either Android phone OS (2.xx) or Honeycomb (tablet).
Just like there is no current netflix streaming app on Android. Think the issue has to do with Android's lack of security for their users illegally downloading streams.
But you can stream in Android browser because it supports flash. I've done the espn 3 stream in my Samsung Galaxy (Vibrant) and flash is horrible on a lot of websites. I'd rather had an app with official support anytime.
