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.
