There are still questions as to how, when, or where Chromecast mirroring will come, but one thing is certain, mirroring is here.
Famed developer Koushik Dutta prompted a number of comments with his announcement on Google+:
Koush didn’t explain any further on how he accomplished mirroring, I’m definitely excited to see.
There definitely some issues — particularly with lag — but I would expect this to work very much like Miracast (which I’m enjoying using with my Nexus 5).
Needless to say, I’m going to sit and press the refresh button my Google Play apps list — Koush developed AllCast app.
