plane object, clipped_by box object (not subtraction or union) with texture and
interior_texture.  This gets a rectangular one way mirror, no thickness though.

plane{z,0 clipped_by{box{<-30,-30,-10><30,30,10>}}
  texture{
    pigment{rgbt 1}
    finish{ambient 0 diffuse 0}
  }
  interior_texture{
    pigment{rgb 1}
    finish{ambient 0 diffuse 0 reflection{1}}
  }
}
