Web objects in 360 Rise

Does Rise support WebGL content?  Similar to Alex's point above I would want the freedom to design and create custom content ( learning interactions / 2D or 3D games, animations, 3D models, etc. ) and then plug them into Rise.  I would of course be creating this custom content using other tools such as Adobe Muse, Unity, Maya, Dreamweaver, Flash, iClone, CrazyTalk, After Effects, etc.  Most importantly, though to me would be the ability to use Unity and publish to WebGL and then take that WebGL output and drop it into a Rise project.
