With c) you're allowed to run up to 2 copies. It doesn't really help you run a hundred containers on a powerful server... (Not that you easily legally could, as I guess the moat powerful Mac hw available is the Mac pro - not exactly great for rack deployment).

[ed: i guess you mean running os x server is an alternative to "non commercial use" - I agree with that reading. The option for nc use seems like a nod to not completely make experimentation and creative development/research entirely illegal.]
