That is when conversations bearing sounds like mpscp and uftp begin and then someone says "aw, screw it, just send them a disk".

I've never claimed to be particularly bright, but I do like to challenge assumptions.
It isn't only the amount of bandwidth available but also in many cases the protocols used to transmit the data. It takes smarter than the average bear to figure out how to get data across a fat pipe over a long distance at a high rate. TCP protocols are limited by the number of packets allowed to be "in flight" according to how the stack is configured. One might need to go to unorthodox or rather new methods to use all the available bandwidth.
There are many cases of someone being stymied as to why they can't even get anywhere near 10 megabits of throughput on a GigE path from Los Angeles to London using FTP, for example. In many cases the responsibility of getting data from point A to point B is handled by people who don't bring their network operators into the discussion where problems like this can be pointed out to them. Often the first time the enterprise network group hears about it is when someone complains that the "fast pipe" to $continent is "slow" and therefore must be broken and that is generally followed by the demand that it be fixed immediately if that demand is not included in the first email.
