  Fidelity F{classical} = 1/2 has been established as setting the boundary
between classical and quantum domains in the teleportation of coherent states
of the electromagnetic field (S. L. Braunstein, C. A. Fuchs, and H. J. Kimble,
J. Mod. Opt. 47, 267 (2000)). Two recent papers by P. Grangier and F. Grosshans
(quant-ph/0009079 and quant-ph/0010107) introduce alternate criteria for
setting this boundary and as a result claim that the appropriate boundary
should be F = 2/3. Although larger fidelities would lead to enhanced
teleportation capabilities, we show that the new conditions of Grangier and
Grosshans are largely unrelated to the questions of entanglement and
Bell-inequality violations that they take to be their primary concern. With
regard to the quantum-classical boundary, we demonstrate that fidelity
F{classical} = 1/2 remains the appropriate point of demarcation. The claims of
Grangier and Grosshans to the contrary are simply wrong, as we show by an
analysis of the conditions for nonseparability (that complements our earlier
treatment) and by explicit examples of Bell-inequality violations.
