I agree that on a high traffic network such as that, the burning speeds
should be lowered considerably. It is possible to allocate a percentage
of the network to allow for a dedicated transfer of this data, but that
would reduce the amount of bandwidth available to the rest of the network.
I am still unsure as to whether or not Windows will natively supports
buring a CD over a network. I do know that such programs exist as I have
tested them out. Take a look at Nero NET:
