The SlingPlayer app from Sling Media will play video from and allow you to control your home media center over 3G or WiFi. The app controls a Slingbox, a piece of hardware that sits in your home and relays your media to anywhere you’ve got signal. The app can change the channel and even control the DVR.
They had the SlingPlayer running on a Nexus One, a Motorola Droid, a Samsung Behold 2, and an iPhone. The Android UI wasn’t quite done but was expected to function similarly to the iPhone app.
They expect to be ready to launch by this Summer so we should be seeing some live video in your hand within just a few months.
