title: iBeacon, AltBeacon, *Beacon: What interoperability is legal, and permitted on iOS and Android?
body: <p>I want to support only one Beacon standard if possible, and have the device itself act is the "host/beacon", and other devices the "listener".</p>
  
  <p>I'm supporting Android, iOS, and possibly Windows phone using Xamarin.  </p>
  
  <p>Is any interoperability supported between iOS and android? </p>
