Actually, I am reusing the SOCKS4/5 code. The difference is that now request are also accepted over the multiplexing UNIX socket created when ssh is run in master mode.

The problem with INET sockets is that there is no way* to control who access then. Even if they are only bound to localhost, in multiuser machines, any local user can connect to them.

On the other hand, access to an UNIX socket can be controlled using just file permissions, so that, for instance, only the user running ssh could connect to it.

* well, unless you add authentication support to the SOCKS4/5 code, but IMO, that would be something really complex to manage and to use.
