as noted elsewhere in this thread, clients don't cache things, so the only benifit of sending the extra things is if you are running a cache. since you are able to control what software gets used on the XO, you can make the DNS cache be one that applies rules that allow you to send the extra stuff that you want. but I think that is probably not a great idea as it can break if that package gets changed upstream to follow a different set of rules.
