Every so often, it writes a file containing a snapshot of who is online and who is not in your contactlist to a location you specify. This can be a local file, an FTP server, a HTTP server, or anywhere else that TDEIO can access.
Goal is to allow ppl who don't have us on their contactlist to see what our current status is and what our UIN/id is for each protocol. So we need to know (protocol, uin, status).
