Well, if we update the example a bit, at 16 Gigabytes/pound for optical disks, a one-ton pickup truck full crossing the country in three days has a bandwidth of 126 MBytes/sec. Which is pretty good, but the delay is awful. Do you know how long it takes to write 32 Terabytes of data? (Actually, the cost isn't too bad either.) -- Lyle Wang lws@capybara.comm.wang.com 508 967 2322 Lowell, MA, USA Source code: the _ultimate_ documentation.
