Yes, even today, for large amounts of data, the speed and cost of moving a physical medium can be much better than that obtained by transmitting pure information. It's instructive to compute the baud rate of a mundane 1600 BPI tape flown from NY to SF in 6 hours. And of course, you can easily increase the effective rate by an order of magnitude by simply sending 10 tapes at once. For Doug's case, assume an optical disk means a CD, holding 600 MB. For micro users, the cost of downloading a "free" program from, say, Compuserve may exceed the cost of buying a disk with that program on it! -- Howard A.
