Integration Broker - FTPTargetConnector to do a 'GET' on a XML file

Regarding using a FTPTargetConnector to do a 'GET' on a XML file we can pickup the file from the ftp server for processing. However,since there is no ListeningConnector for this particular connector type so IT DOES NOT listen for any incoming requests /updates from the ftpserver. I am told I will need to create a process which executes the requests that goes out and looks for a file and then 'GET' the file and then write Custom Code to Subscribe to payload. There is no delivered mechanism for this particular connector. Has anyone done this that would be willing to share????
