I solved the framework problem by using an upstart script to run my eventlauncher.sh
This proved to work really fine.
I'm using about 5 differents events for Komic and I'm planning to use more!
On the other hand, I'm working on the dual problem: send an event from a custom script and catch it inside a WAF.
If I manage to do this, we can finally have a full working "communication service" to/from WAFs.
