Ever considered system-wide remote dns for network proxy?

The kind of remote dns that firefox has (or other browsers have).

Firefox remote dns setting:

For proficient users, they could choose proper iptables rules to redirect all udp-port-53 traffic to some sophisticated socksifier software, then use the socksifier to carry on the traffic to system network proxy.

But for less experienced users, theses steps seem insurmountable.

That's why I think we need this function on Ubuntu. And it would be better if it's possible to exclude some local ip addresses as firefox does.

With all that said, I can fully understand if final decision is made that this function should not be put on the priority list.
