[NTG-context] U3D (embedded 3D objects)

Hello, is there support for .u3d files in ConTeXt available or planned? This would take advantage of Acrobat 7 support for these 3D data files. There is a LaTeX package (http:// www.tug.org/tex-archive/macros/latex/contrib/movie15/) that does that, and it even works on my Mac. Thanks, Matthias
