[c-nsp] Rate-limiting You Tube tarffic

[Troy Davis]

One option is a transparent proxy like Squid.  Direct and embedded 
Youtube URLs are fairly consistently constructed; as long as you can 
filter based on the HTTP 1.1 Host header, blocking *.swf from 
*.youtube.com would prevent movie playback.

Folks could use Tor, Privax, or another URL forwarder to get around it. 
  I think most would just switch to other user-generated video sites 
like Vimeo, Liveleak, or Miro.
