That's an interesting effect of dual licensing, but I'm not sure I understand it right. If you write a routine that uses the `chol` command, that's not a derivative work of chol, is it? It's just a function call, which is a normal use. It seems like if you give someone this routine but don't give them CHOLMOD, they can use any implementation of that function signature they wish. But maybe since it's an oct-file (or I imagine a mex-file in MATLAB), it's baked into the interpreter and it's a different story.
