I reached exactly the same conclusion. I would recommend against the  
mod_rewrite hack because it is not a full implementation of content  
negotiation. mod_negotiation works great for static files, for  
everything else you should probably code your own solution. (And  
everyone who codes their own solution gets it wrong the first time ;-)

In practice, content negotiation is quite an interoperability  
nightmare. One more point pro RDFa, I suppose.
