I would like to be able to use a ChromeCast as a player. It is super easy to setup and only $35! The problem is that due to the nature of the Chromecast to be an easy and pretty open setup and use, the device auto applies any command sent to it. So, if I send it the URL of my RiseVision Presentation and some enterprising student decides to open Chrome and screen cast a different URL to the Chromecast, it will just switch to that... The problem here isn't RiseVision, but rather securing a Chromecast...anyone know anyone at Google?
