Suppose an organization decides that they've had enough of trojans, so they l decree that everyone gets the approved desktop image and noone may install the software they need to do their job effectively and efficiently. To enforce this, employees get only a very limited account on the machine, similar to the default Guest account in Windows.

The result? The IT department no longer knows what software is being used since employees have to keep it secret (or be unable to do their job effectively). They don't know how the software got there. Maybe a lot of people are doing their work on personally-owned laptops or tablets, so company data is now handled on the same system their kids use to play online games.

First, if anyone can get to your "shit-ton of data" you are not doing it right

"One person" may only stream one video at a time, but "people" as a whole may stream thousands or tens of thousands of videos all at the same time, and that's what creates the bottleneck in the peering connection. These same "people" are the "people" who currently stream videos over Comcast et.al. and create the peering bottleneck between Comcast and Level 3.
