  No, I have not even heard about it.  Is it used in the next edition of
  TAoCP and the remaining volumes?

  Heh, I like.  That probably also means Unicode characters, instead of the
  rather bizarre character set used in MIX. :)  It might be more work to
  implement an emulator, however.  A MIX emulator is not that easy, either,
  due to the TeX-like random complexity.

  I would worry more about the cost of context switching on this design.
