Solved this. If anybody runs into the same issue, here's the solution:
-Make your text object
-Put it inside an empty game object (GO)
-Place the position of the new GO at the center of the cylinder
-Place the text game object at the surface of the cylinder
-Get your camera rotation (every frame) as VectorXYZ
-Use Set Rotation and apply (in my case), the Y value to the GO every frame
-Use 'Self' space (my ultimate issue...)
HTHs somebody
