Standardize SOCKS extensions to support proxied DNS queries
Tor supports anonymous DNS resolution through its SocksPort, but no application (except the
tor-resolve utility shipped with Tor) uses that feature, probably because it's not an IETF standard. Perhaps that should be changed.
This will probably involve designing a new DNS-resolution SOCKS command and implementing it in Tor; Tor's current SOCKS commands are not likely to be accepted as a standard (even if they're renumbered) because they do not support most of DNS's new and interesting features.
