What has this to do with logs/logging? Anyway, the simplest method of sharing such data is using a database engine. Not necessary a heavy one like SQL Server - Firebird would do it, aspecially as it implements event model, so you can notify users about changes. An other approach woud be using share folder (i mean SAMBA, windows sharing) and using
FileSystemWatcher[
^] in the clients to monitor the same folder. This won't work if the clients are in totally different networks.
