The Iris 3D site was updated with this news:

“Iris is now very stable. I added some sample code and a class reference for people who would like to play with it. I’m currently working on a little game to show some physics.”
This engine is particularly impressive and comes with some great documentation, so hopefully we will start to see some developers using it in the near future. If coders are not willing to use the direct pvr api, and would rather use a higher-level api such as KallistiGL, then this is an excellent alternative.”
