Hi Anne,

I think the general feeling here is that by calling out sniffing as a  
possibility, it will encourage it. As it stands, sniffing is not  
prohibited, it just isn't advertised as something that should be done.  
I.e., the content sniffing spec will NOT be in conflict with HTTP.  
Does that work for you?
