communicating with Growl?

Is it possible to send / recieve notifications to and from growl on mac os x?

Im wondering if its possible to use an LCD screen connected to arduino to view growl notifications transmitted over from the serial?

From a quick look at the Growl docs, there are many scripting language ways to trigger a Growl notification, but I didn't see any built-in serial port monitor. You could make a simple Perl or Python (or maybe Applescript) that watches a given serial port and turns the incoming data into Growl notifications.

I am not sure if there is any support for the other way around, where your script is notified of any Growl events that you could pass to the peripheral.
