[edit] Converting with Rotation

If you need to export with some transformation, you can do this by setting passing the GLOBAL_MATRIX variable to export_fbx.write()

The GLOBAL_MATRIX (example shows a rotation matrix, but you can use any matrix, change the values for the transformation you desire)...

GLOBAL_MATRIX = Blender.Mathutils.Matrix([1,0,0,0], [0,1,0,0], [0,0,1,0], [0,0,0,1]),\

If you'd rather not enter in the exact matrix you can use a function to create a rotation matrix...

GLOBAL_MATRIX = Blender.Mathutils.RotationMatrix( -90, 4, 'x' ),\

or multiply them...

GLOBAL_MATRIX = Blender.Mathutils.RotationMatrix( -90, 4, 'x' ) * Blender.Mathutils.RotationMatrix( 180, 4, 'z' ),\

Note, some applications will raise errors when bones are scaled (Maya, 3dsMax and Lightwave. so its best only to use a rotation/translation matrix)

See the RotationMatrix documentation.
