Growl/Snarl could notify you of many XMPP related activities.
I saw that Skype, Psi and Adium use Growl for all kinds of notifications (and many others too http://growl.info/applications.php?cat=Chat ).
I believe they did not want to invent yet another "Toaster" window.
Has anyone of you thought about using Growl/Snarl as a generic notification system? Here I found a Java 4Snarl library (http://www.dotti.at/Snarl4Java/ ).
PS: Should I ask this question better to Smack Dev instead of here (e.g. creating a bind to Snarl using Smack)?
