Miracast is explicitly designed for screen mirroring - Chromecast is not. Miracast has been built in to various Androids since 2012, and is now part of the Android codebase. It's peer-to-peer. Chromecast does everything through your router - an access point. It was designed to receive content from the internet, with control by any device on the same home network. Bottom line in my opinion - it's going to be very interesting to see how Koush has solved the technical problems. As mentioned at XDA, it's probable that this is not going to be a gaming display solution and it's going to be interesting to see how Koush is maintaining video/audio sync for things like movie playback. But - we're about to see.
