A few days ago, a pair of apps called RemotePlay and RemotePlayM by new Android developer Piddas21, a subsidiary of Taiwanese Quanta Computer, hit the Play Store ahead of SXSW. The idea is great - media and document sharing in real-time, across multiple platforms, such as Android, iOS, and Windows 8. Want to easily stream a video from your Nexus 4 to your iPad? No problem - it should be as simple as dragging it to a bucket with your iPad's name on it, and voila - you're watching a video on the big screen.
Note: At the time of this writing, both the iOS and Windows 8 versions were still in development, though they should be coming soon.
