If it supports both chromecast and some reasonable open protocol screen sharing, I&#x27;d really like to upgrade my chromecast stick. While I&#x27;m usually happy with android&#x2F;chrome integration, there are times when I want to cast some app, or even someone else&#x27;s itunes. Currently that&#x27;s not possible.<p>If this can destroy some garden walls, I&#x27;ll be happy to pay.
