We had mention of this in another thread already. But I really think that these kind of questions should be reversed to something like "Does CCCam support ipbox9000?".
Companies have more important things to consider when choosing the cpu and platform of their boxes then whether will Cccam work on it.
It makes much more sense for cccam team to compile sh4 version of their emu then to expect from receiver developers to adjust hardware to cccam. But they seem to stand behind dmm with their decision on which platforms to support. But maybe it is still too soon to say.
