----------------------------------------+-------------------------
 In Paris, dgoulet and I started to write some basic torsocks support for
 SocksSocket (#12585) - in an ideal world, we'd have a Tor with a
 SocksSocket running by default. This would allow torsocks to do useful
 things by default - namely - any app can be instantly torified without
 worries about firewalls, users can be isolated from different socks
 proxies by uid, etc. Basically, I think it means that torsocks could
 default to SocksSocket, if built on a SocksSocket supporting platform.

 I think for changes, we'd want to do the following:

   Add a configuration (in /etc/torsocks.conf ) option for the default
 SocksSocket location
     eg: /var/lib/tor/SockSocket
   stat() the default SocksSocket file location
     if we find a SockSocket, we switch to AF_UNIX for all communications
       normal torsocks failures from here out
     if we don't find a SocksSocket
       fail hard? fail soft?
   if we fail soft, switch to the default _server_ configured
     if that fails, give an error and fail hard

 dgoulet - do you still have the patch we started to write in paris?
