This is 100% canon. I have the Skype logs to prove it. I ensured that RaddaRaem got into that stream, and got some cool art that he hasn't posted yet because he is even lazier than I am.
The third and final piece I got during that night, not counting some drunken doodles that seem to have evaporated. Yuroboros did a fantastic job of rendering characters they only just heard of, and I particularly love how they rendered the joints of the roboarms. Need to remember some of those details the next time I shove the head moof at someone.
