I need to send an acknowledgme

Answer 1

Writing and reading from a socket are separate. You can try to close a socket for writing and leave it open for reading.

See http://docs.python.org/library/socket.html#socket.socket.shutdown

Also, what FTP does is use two sockets: one for data, and one for this "confirmation".

You'd be happier using a second socket for this additional metadata.
