imaging computers

Ok, I have norton ghost, and was wondering if there was a fast way to image a group of computers over the network, with one computer being the master, and the rest being slave. Also, is there a bit-by-bit option with ghost? I cant seem to find it. If ghost does not have a bit-by-bit option, what other programs can do bit-by-bit, full hard drive copying over the network? (dos or otherwise)
Thanks.
