For this to work, servers would first have to implement RFC 2295 and
send appropriate Alternates response headers (otherwise UAs wouldn't
have any mean of discovering variants); unfortunately, I don't know of
any web server doing so (even Apache, though it uses an algorithm
inspired from RFC 2296 for negotiation, AFAIK).
