While we're talking about possible things for C2, how about the ability to use the full suite of procedural textures in conjunction with volumetric lighting (the light cone in C's case). Currently you can use your light's gel on the light cone fog but I haven't found a way to apply arbitrary procedural textures such as cellular (or something like noise factory). Interestingly, C appears to have more options for straight light gels than lightwave (which appears to call them projection images and only seems to allow texture maps but not any procedular textures for gels). There are several things like this I've found where C seems to be more advanced than lightwave. Here's a look at what you can do in a few minutes in lightwave with volumetric light and procedural textures.
