There have been a few other machines like this showing up over the last
year or two, at least one of them was using a fair bit of earth in the
mix, though I don't recall any including straw and I think all of them had
at least some cement in their mixes.  It does at least present a possible
approach for taking cob more into the mainstream, though a cob based
machine would probably be quite a bit more difficult.
