  To determine whether the Shapiro time delay of light passing near a moving
object depends on the ``speed of gravity'' or the ``speed of light,'' one must
analyze observations in a bimetric framework in which these two speeds can be
different. In a recent comment (gr-qc/0510048), Kopeikin has argued that such a
computation -- described in gr-qc/0403060 -- missed a hidden dependence on the
speed of gravity. By analyzing the observables in the relevant bimetric model,
I show that this claim is incorrect, and that the conclusions of gr-qc/0403060
stand.
