Contest closed! MultiMod it is.

I'll play around with the idea later when time permits to see if it might actually work.

No problem.

I have been doing embedded product development and manufacturing development for years, I can attest that creating a prototype and creating a finished product is not the same thing.
Also, creating a product in a tiny production context (like here) or in a small volume productions context (20K units/month like I am used to), is also a different ball game.

True but hard.
