the class FileTransferNegotiator method negotiateOutgoingTransfer.

/**
 * Send a request to another user to send them a file. The other user has
 * the option of, accepting, rejecting, or not responding to a received file
 * transfer request.
 * <p/>
 * If they accept, the packet will contain the other user's chosen stream
 * type to send the file across. The two choices this implementation
 * provides to the other user for file transfer are <a
 * href="http://www.jabber.org/jeps/jep-0065.html">SOCKS5 Bytestreams</a>,
 * which is the preferred method of transfer, and <a
 * href="http://www.jabber.org/jeps/jep-0047.html">In-Band Bytestreams</a>,
 * which is the fallback mechanism.
 * <p/>
 * The other user may choose to decline the file request if they do not
 * desire the file, their client does not support JEP-0096, or if there are
 * no acceptable means to transfer the file.
 * <p/>
 * Finally, if the other user does not respond this method will return null
 * after the specified timeout.
 *
 * @param userID          The userID of the user to whom the file will be sent.
 * @param streamID        The unique identifier for this file transfer.
 * @param fileName        The name of this file. Preferably it should include an
 *                        extension as it is used to determine what type of file it is.
 * @param size            The size, in bytes, of the file.
 * @param desc            A description of the file.
 * @param responseTimeout The amount of time, in milliseconds, to wait for the remote
 *                        user to respond. If they do not respond in time, this
 * @return Returns the stream negotiator selected by the peer.
 * @throws XMPPException Thrown if there is an error negotiating the file transfer.
