Seems like a step sideways to me.  Charter probably already has
HTTP interceptors in place, so they could just as easily block DNS
over HTTP.

Maybe we should wish for DNS over SSL/TLS (dnss?) and skip the HTTP
part.  But I doubt guys like OpenDNS would be eager to the SSL
handshakes with all their clients either way.

How long until domain/content owners realize that its better
to have a wildcard than to return NXdomain?
