Display camera output in Windows Phone 7

Question

I am writing an augmented reality application for Windows Phone 7 as a school project. I want to get the camera output, and then add a data layer on top of it. Is there any way for the camera output to be displayed on the panel?

FYI: on the Windows Phone SDK 7.1 (aka "Mango") you can now write applications that use the device’s camera as you describe. See the App Hub for a link to the latest 7.1 development tools. The documentation describes how to do this at the following link:

CameraCaptureTask:

public partial class MainPage : PhoneApplicationPage

   // Declare the CameraCaptureTask object with page scope.
   CameraCaptureTask cameraCaptureTask;

   // Constructor

      InitializeComponent();

      // Initialize the CameraCaptureTask and assign the Completed handler in the page constructor.
      cameraCaptureTask = new CameraCaptureTask();
      cameraCaptureTask.Completed += new EventHandler<PhotoResult>(cameraCaptureTask_Completed);
   }

   // In this example, the CameraCaptureTask is shown in response to a button click.                
   private void button1_Click(object sender, RoutedEventArgs e)
