> What I propose is to add the possibility to connect to a remote SSH server through an
SSH connection stream (instead of an HTTP or SOCKS proxy). See for instance
> http://backdrift.org/transparent-proxy-with-ssh
> for a use case.
> This simulates a ProxyCommand where the command is run on a SSH host.
> The patch also contains a test for the new functionality. 
> Example of use (with the netcat command nc -q 0 HOSTNAME PORT)
> {code:java}
> builder.setProxyType(opts, SftpFileSystemConfigBuilder.PROXY_STREAM);
> builder.setProxyCommand(opts, SftpStreamProxy.NETCAT_COMMAND);
> builder.setProxyHost(opts, "gate.way.host");
> builder.setProxyPort(opts, 22);
> builder.setProxyOptions(opts, proxyOptions);
> {code}
