Maxwell or C4D is fine by me. I just recently started using maxwell so I'm still learning the nuances, but I was able to setup a 3 machine render farm using the trial versions in a matter of minutes. Also, I think Maxwell is a less expensive product than C4D, but I'm willing to put it to a vote. If the demand is high enough, there's no reason why both can't be available.
As I said, I haven't really put much thought into it, just wondering if there's enough demand to warrant the time/costs
Part of the reason I bring it up is that after spending a few weeks reading through a decent amount of posts/threads, the one common complaint is the amount of time the renderings take. While I expect the casual user won't spend money to get their renders done, those who are in a time crunch could use a more economical alternative than some of the cloud renderfarms.
But you could be right, this could be a totally pointless topic, but at least it can serve as reference for anyone else who might have a similar idea
