Comment:

 Did you mean for this to happen on the exit node, or elsewhere?

 The problem with doing this as the exit node is that there are programs
 out there that assume that any connection coming from 127.0.0.1 is coming
 from the local computer, and use that as a kind of rudimentary access
 control. They assume that connections from 127.0.0.1 are more privileged
 than those from other IPs. That's why Tor exit nodes block 127.0.0.1 by
 default, as well as all connections to RFC 1918 networks (and some
 others).

 Can you explain more about the use case here? With this change, what could
 a user or admin do that would be hard for them to do today?
