Do you have plan to support publishing multiple pcl::PointCloud<T> or
PointCloudArray.msg the feature official release of PCL_ROS?
I encountered the same situation when I'm trying to publish the result
of SceneAnalyzer of OpenNI/NITE which is to publish point cloud data
for each segmented human volumes.
I thought other people require same message type when they build the
node to publish , for example, multiple planner surface, cylinder
object  in the point cloud data. Or, is there other way for them?
