Shipping disc by air or boat is quickly way to go between two countries, but inside country bandwidth is good enough to not need to send discs. In China (an example) we install software on school PCs from central location (Ministry of Information in capital city) but do over the internet. It's fast because we have fibre-optic links country wide for data distributions.
Obviously, this is bad idea if want to send gigabites to America or Europe because of the bad connects you have with China, but inside country, internal network is much faster than sending disc, unless you want to send 1000s of hard disc at a time!
