Since user agent negotiation is just a special case of content negotiation, 
we should definitely merge the two together for now.  HTTP-NG profile 
negotiation sounds nice, though...

David: I am still unclear from what you have written as to whether you are 
fighting browser bugs (tags not displayed properly, memory violations, etc.) 
or fighting presentation issues?  My firm hope is that as both major browser 
vendors move to style sheets, that much of the "negotiate on user-agent to 
enable proper presentation" stuff can go away.
