not really, AOKP uses some CM9 stuff, but its definitely a proper ROM on its own.
Any rom that says AOSP in its name is generally Built from google source code, with little to nothing from CM7/9 other than what might be necessary to get things running.
MIUI is another rom that, while built from CM7/9 is VERY different.
ROM's like Hellfire, and others similar to it, are mostly just a proper CM7/9 ROM with tweaks, and small fixes put into it, and more recently (to my annoyance) other kernels too.
Overall, CyanogenMod was probably the greatest thing to happen to android modding as a whole, they provide a base for most things to branch off from (and they don't even complain when everyone and everything uses their source!) The only reason its in everything is because if its something that the user will not see, and it works, why spend the days/weeks/months to develop it when its sitting right on CyanogenMod's GIT.
