  In view of recent developments in the investigation on cuprate high-T${}_{\rm
c}$ superconductors and the spin-Peierls compound CuGeO${}_{3}$, we study the
effect of dilute impurity doping on the spin-Peierls state in quasi-one
dimensional systems. We identify a common origin for the emergence of
antiferromagnetic order upon the introduction of static vacancies, and
superconductivity for mobile holes.
