This is an interesting discussion and it illustrates something that  
we have a tendency to forget often at W3C.

The discussion is around this.

* Some resources are available on the Web with the wrong mimetype

	- Servers do a bad job because often of misconfiguration.
	- Browsers do content sniffing because of this

-> Then vicious circles or chicken-egg problems.

All of that is perfectly logical and we can throw stones to one side  
or the other and it will not achieve a lot. I'm more interested at

	"What would be the mechanism to improve
	the implementations and the bad situation of mime type?"

Fixing implementations is a noble goal and I'm pretty sure Ian is  
doing that a lot. Taking care of the user is a noble goal too.

I see one missing player in the debate we are having: "Authoring  

Authoring a resource is a mix of server-user agent interactions.  
Because of history and bad support of HTTP PUT, the creation of  
resources has escaped for a long time the Web paradigm. Creation of  
resources is not done on the Web, but most of the time in another  
space (database, filesystem, etc.) then the resource is "made  
available" on the Web (scripting, FTP, etc.).

The issue is here. When we create a resource on the Web, how do we  
	1. It has the right mimetype
	2. The mimetype can be changed by the owner of the resource (or his/ 
her tool).
            (Right now the mimetype is "owned by the server")
	3. How a user agent which would have done a successful recovery  
could suggest to the server and the owner of the resource that the  
mime-type is wrong.

Basically how to put in place a programmatic way of improving the  
state of content-type on the Web by modifying servers and tools which  
create resources.
