As per a Chromium code review
According to code review entry, the app currently performs the following actions:
- Authenticate using a Google account on the phone
- Query and display the host list from the Chromoting directory server
- Connect to and communicate with the host service over XMPP/ICE
- Establish peer-to-peer channels for communicating with the host service
- Notable missing features are: Display the host’s desktop, Handle any kind of input
While, Google Play is still full of apps that offer similar functionality, it is always good to see an offering from Google.
