[info-tech] MYSPACE and FACEBOOK

[Richardson,Tony]

Hello All,
 
Has anyone out there found a way to actually stop the use of MySpace and 
Facebook on school networks? These HTTP Proxies appear to be unstoppable. Is 
there some kind of "signature" for these two social network services that I 
could use in the Intrusion Prevention Filter on my firewall?  HELP!
