Well, you then need proxytunnel or similar enabled since a proxy by definition
is terminating the connection a client makes, and the proxy then makes the
rest of the communication for the client to the remote server.

You shouldn't allow libcurl to send anything, use CURLOPT_CONNECT_ONLY,
CURLOPT_HTTPPROXYTUNNEL and then curl_easy_getinfo()'s CURLINFO_LASTSOCKET.

Uhm, yeah that would be an alternative. To allow CURLOPT_CONNECT_ONLY with SCP
or SFTP and then have a feature similar to CURLINFO_LASTSOCKET that instead
returns the libssh2 session handle. But I'm really not liking the thought of
having that ability in the API. I think it's bad enough already that we can
export the "raw" socket like this...
