The main cameras view matrix could be added as an extra uniform, the main cameras projection matrix too? However. one will have to careful about all of this, if you need something to be the same across all cameras then it really needs to be in world coordinates, this way all cameras will get the same value for it, so if you are getting problem perhaps it suggests that something else needs to be tweaked along the way w.r.t the algorithm. This is in effect what I was talking about when suggest the use of position lighting source rather than a directional one.
