Hi,

Maybe I missed to interpret your question.
It is technically easy to utilize SSL-tunnel (over a HTTP proxy) to invite
TCP connections from outside, but what is difficult is not there but in
another, legal or ethical, layer.

 | |                   DeleGate                  DeleGate
 | |  FTP ----(FTP)--- FTPxHTTP ----(HTTP)---- FTPxHTTPserver (---

 | |client      |       client    (or HTTPS)        |
 | |            |                     |       (local-files)
 | |        RETR/STORE                |
 | |        LIST/MSLT            GET for LIST/RETR and others
 | |         MKD/RMD/...         POST for STOR
 | |
 | |See <URL:http://www.delegate.org/mail-lists/delegate-en/04810> for more
