RAS should start using BitTorrent for videos, eh? At least the videos
worth keeping around for awhile.

Downloads with BitTorrent are faster since your BitTorrent client
trades pieces you have with pieces your peers have. Your net download
speed isn't limited by the original server's or any single source's
bandwidth. Bonus, the original server's bandwidth utilization isn't as
high.

Just leave the BitTorrent client open after the download to assist with
distribution. No security risks. No one may retrieve any other bits on
your computer, just bits from the files downloaded in the current
session.
