I want to be able to modify the host that the user program is
requesting from the Tor SOCKS proxy.  E.g. Firefox requests abc.com,
Tor receives a request for xyz.org.  And I want to do this without
modifying Tor's source code.

The intended use case is redirecting .bit domains to .onion domains
(as a way of enabling human-readable .onion domains), without needing
any modifications to Tor or TorBrowser.  (Also redirecting .bit to
.b32.i2p domains would be an application.)

My understanding is that the main quirk of Tor's SOCKS implementation
is that the SOCKS basic auth is used for stream isolation, so passing
it through from the user to Tor shouldn't hurt anything.  Is there
some other deviation from the SOCKS spec that I don't know about?

Thanks,
