In terms of appliances, I think Packeteer and Sandvine have appliances  
that shape very well in the way you are describing.  Pulling the HOST  
out of the HTTP and throttling back *.facebook.com regardless of IP  
address.  However, shaping by IP address is a lot of work for HTTPS  
and is a lot more problematic.  Currently, most rich media websites  
don't use HTTPS for serving up their heavy files.  Additionally,  
throttling by IP for media rich websites can be an issue because an IP  
fro Akami or Cachefly may service Facebook.com, Yahoo.com,  
MySpace.com, Revision3.com, and FAFSA.gov leading to some unexpected  
throttling, which isn't that big of a deal unless you're blocking.
