I believe there is an option for "simple connection" (CURLOPT_CONNECT_ONLY),
it seems to be designed for HTTP-like connections (you'll probably have to
fake the connection url with something like: http://ip:myport/).
You then use curl_easy_getinfo(handle, CURLINFO_LASTSOCKET) to retrieve the
socket and communicate in place of cURL.
