Ja.  The notion of required low-entropy energy reflection is based on an
assumption of passive cooling only, with no fluid flow heat transfer.
Robert never liked that idea, for he was a big fan of (or believer in)
strong nanotech.  I would like to accept the notion, but I had in mind a
device which could produce MBrain nodes using current or almost current
technology.  If Skylon flies, we could start launching them in our
lifetimes.  

Robert might argue that the MBrain concept depends on strong nanotech and
perhaps strong AI, but I have envisioned an MBrain concept which could
predate both, or could exist even if some unknown-unknown makes strong AI
and strong nanotech impossible.

Perhaps, but having everything in text has its advantages too.
