I think part of the problem is that the structure of firewalls, NAT 
gateways, and so on, encourages many uses to 'hide' inside HTTP.  For 
example, all of the trailers on the Apple trailers site are HTTP 
loaded.  Do they count as general web or multimedia?  Or is all that 
bundled into web media?
