I think , that power part of the design is not going to be bottleneck , here.
The SPI will be pain in the ass, You will have to use some kind of level shifting.
RPI is too much of a mess for my taste too

Yes you are right , but:
5 V 1.2 A it is what - 6 W
with 6 W with theoretical specs current 16 nm generation of Bitfury you will get roughly 50-60 Ghs tops and the chip will be hot as hell, so the device will need good coiling - heat sink alone will have trouble to handle the heat or it have to be oversize .
This is my reason

Two different 16 nm chips you say.
I suspect you are under NDA, but if I speculate and say this might be Bit fury and Bitmain.
Correct me if I'm wrong.
So from here you steeped on ground level 0 at least

I know a person that had one sample for design tests a few months ago , but not sure what happened next .
Just out of curiosity.
Has anyone (except people directly related to BitFury) got there hands on one of BitFury's 16nm chips, or maybe is there anyone who bought the containerized solution? And if yes, what are your experiences with either of the 2 (chips and/or container)?
Or is BitFury's typical answer that the minimum order quantity is 1 million USD, without stating how many chips that would be, and that their 1st batch is sold out
Furthermore, seeing that the minimum investment needed is apparently 1 million USD, I wonder whom they addressing when the thread reads "16nm...sales to public starting shortly", and how is this supposed to help decentralization of the BTC network as was stated in the quote of the 1st entry in this thread?

So, as mentioned earlier, the proof-of-concept I'm working on now is based on the Avalon A3218. As there isn't a publicly-available datasheet on the A3218, I'm assuming the protocol works about the same as documented in the A3222 datashet.
So today I started setting up a test rig to establish SPI communication with one of the chips. But I need to know what data to send it. If anyone's got advice on this, I'd be happy to hear it.
Specifically, stuff like the A3222 datasheet gives three clock configuration segments, but I don't know why. And especially a means of calculating the midstate and other preprocessed values (a0, e0, etc). I'm spending time parsing through cgminer code, but by now there's a heck of a lot of cgminer code to look through and I figure surely after 3 years of Avalon products in the wild someone knows how those calculations work. Mostly I just need a valid sample I can push to the chip and see if it talks back with something that seems in any way "correct".
And yes, if it helps motivate someone to assist a bit, I will try to implement an A3218 stickminer based around this work.

I've always used MCU to communicate with Avalon chips.
A3222 was similar to gen 2 and 3
I can dig for the code for 3222 I'll be able to do this in my old lab
It is a firmware cod in C
Well right now Kilo is pretty much the designated agent for getting chips. My conversation with Punin got as far as giving him some info to make out and send me an NDA around the end of January (which I never received) and then about two weeks later he dropped a line mostly to let me know he'd posted the 28nm info stuff. That's pretty much it.
I have 2 other people that are actually communicating with me and I will have the chips when they are released.
But... when production run will be available and if they are going to sell small quantities or samples is another question .
I think that it is not only up to Punin and big USD will talk
You are not exactly right.
I do not know the details, but most probably the chips order from bit fury would take 2-3 months.
The risk that this integrator takes is big and they are trying to secure sales .
The thing is that the pre order market is over long ago back in 2013-14 and only integrator with good own or investors money can do the game
