Comment (by simonpj):

 Great news!  Doaitse writes "I have found a student with whom I will
 embark on the endeavour to construct a solution to this (I have some
 hopes); either we will have to show a solution, or we will have to prove
 that this is "impossible". I hope to be able to use the kind of
 transformation techniques we have developed in the attached paper".
