Roku has released support notes that strongly suggest the streaming player is about to get a mirroring function. Update: Yep. Roku just announced that it now supports mirroring in beta for Android and Windows Phone devices.
This would let you mirror what's on your tablet, smartphone, or laptop screen to a Roku-attached TV. Awesome.
The feature will be available on Roku 3 and the Roku Stick, and that Android, Windows, and Roku should use the same network to have the best performance. You may have noticed that iOS wasn't on that list of compatible systems, at least for now.
Beta mirroring is already rolling out to customers, and Roku says everyone should have it within the next few weeks. [ZatzNotFunny]
