Unfortunately, no.

I can give pointers to anyone (maybe you :) ) willing to present 
view3dscene :) Some of our interesting features/extensions include 
shadow maps, shaders and compositing shaders, bump mapping, cube map 
(including generation and special 
TextureCoordinateGenerator.mode=WORLDSPACEREFLECTIONVECTOR to easily use 
them), 3d texturing, screen effects. Everything is documented in much 
detail on http://castle-engine.sourceforge.net/vrml_x3d.php (the sidebar 
on the right contains the links), and demonstrated by our demo models 
(http://castle-engine.sourceforge.net/demo_models.php).

As for interoperability, the most important part of the specification 
that I would really like to see fixed is the multi-texturing, that is 
badly broken IMHO (in X3D 3.3 too). I was writing about this a couple of 
times and the list of problems (and my solutions) is on 
http://castle-engine.sourceforge.net/x3d_implementation_texturing.php 
page (sections "Clarifications to X3D multi-texturing specification", 
"Problems with existing X3D MultiTexture.mode specification"). This is 
something that I'd like to talk about and persuade spec creators to fix 
some day :)
