Comment(by nickm):
So, if somebody configured this, they couldn't use any BEGIN cells with a
hostname in them?
Right now, if Tor gets a SOCKS request for "www.torproject.org:443", it
tells its exit node "connect to www.torproject.org:443" -- that's the
BEGIN cell. And the exit node says "okay, I did it -- I connected you to
38.229.70.16:443" -- that's the CONNECTED cell.
But if you've set things up so that 38.229.70.0/8 gets remapped to
something else, then now it's too late: you already made a connection to
38.299.70.16 when you connected to www.torproject.org.
So in order to use this feature, you would need to change how Tor behaves
when its told to connect to a hostname over SOCKS. That's why I said "We
would need to figure out how this would interact with DNS resolution".
