This RViz plugin takes two panospheric images and blends them on a skysphere. The sphere is created directly in OGRE and blending is GL-accelerated. Credit goes to Felipe Bacim whos rviz_textured_quads package helped me to get started.

Make sure you are publishing a sensor_msgs/Image topic for each hemisphere. Load the rviz_textured_sphere plugin and select appropriate image topics.
