Android developers on the Xda forums have managed to get OnLive Viewer running on the Xperia Play, as well as other Android devices.
OnLive is a cloud-based gaming platform that allows you to run high-end games on less powerful computers and mobile devices using video streaming via the internet.
For the time being, Android gamers can only watch other people’s games through the OnLive Viewer software, but the playable OnLive app for Android should be with us in a few months. So far, those tech-savvy Xda forum members have managed to get the OnLive Viewer app running on several Android phones and tablets, including the HTC Flyer, Evo 4G, Droid, and Thunderbolt.
The apk file has been posted for download on the Xda forum topic thread and will work on those supported devices, but you will require a wi-fi connection to stream the OnLive action.
