I am pretty sure Luciano (Lutach) can help us out with parts and RC-Monster forum members with specs and features. Why waiting for CC if they are deaf and ignorant and MGM is way too far, while Quark is lost in space and Tekin is just on horizon.

Yeah, good luck on that. First of all, the hardware isn't simple -- believe me, it's not just sticking some FETs and drivers on a board and wiring them together. Do you know what dV/dT induced turn-on is? Where it can happen? Do you know what current-induced shoot through is? Anyone can create a 10 or 20 amp MOSFET based controller -- but when you get over 100A and the induction voltages are HUGE -- that's when it becomes difficult. Believe me, I've been doing power design for over 20 years and everyone thinks it's easy UNTIL THEY TRY IT.
The first time you see a MOSFET turn on and destroy a controller, while the gate being held off by a driver, and no voltage on the gate, -- then you might know what I'm talking about.
And software -- there's six man-years of development time (and two patents) in the Mamba software. It's not really something that can be slapped together in a couple of weekends.
Oh, and by the way -- I started working on a larger MMM last weekend. Making it a pet "off the clock" project. My biggest issue right now is justifying the cost of tooling... but we'll see. :)
