  Im after the same thing.

  Is there any progress on this matter

  Check the D3D SDK docs, D3DXMatrixShadow Function is well documented and contains all the math and comments needed.

  But that is not a part of the XNA framework right

  I'll take a look to see if this is something we can get in. If not, I'll see about posting sample code that would achieve the same thing.

  Why not write a simple utility function Build your matrix like this:
  
  P = normalize(Plane);
  L = Light;
  d = dot(P, L)
  
  P.a * L.x + d P.a * L.y P.a * L.z P.a * L.w
  P.b * L.x P.b * L.y + d P.b * L.z P.b * L.w
  P.c * L.x P.c * L.y P.c * L.z + d P.c * L.w
  P.d * L.x P.d * L.y P.d * L.z P.d * L.w + d
  
  If the light's w-component is 0, the ray from the origin to the light represents a directional light. If it is 1, the light is a point light.
