How to get point cloud for only one user (for user figure)?

[ghost]

Is it posible get the point cloud data for one user (only the figure)? I mean just exactly like userMaskData (BitmapData) but with depth info like pointCloudData.(ByteArray with XYZ info) Is there a way to do it? Could you add player index info(or label for OpenNI) on PointCloud data, maybe 8 bytes of lenght without RGB and 14 with RGB? Help!
