Inotify-growl is a project mainly written in Python, it's free.
Send notifications to remote Growl daemons triggered by inotify events
I wanted to get messages when files were being added to the local share point. But I didn't want to get one for every file uploaded. inotify-growl was the result of a few nights of work.
BUGS:
Can't run with the -d (daemonized) option correctly yet.
TODO:
Implement logging.*
Implement a file-based configuration system.
ZeroConf for growl daemon discovery on local networks.
