Did you looked at http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPT_PRIVATE
And corresponding http://curl.haxx.se/libcurl/c/curl_easy_getinfo.html#CURLINFO_PRIVATE ?

You can attach any "data" you want to the curl easy handle, and get it back (with correct down-cast).
I think this should do the job for you (with no changes in curl code).
