It will be a nice addition to PEAR, even if i won't have a chance to use it in near future.
After i've saw a live demo, i would said Nice, but where is the solution for PC ? i'm jealous ;-)
Just few comments about code:
- copyright year notice is a bit old (2004) and should be up-to-date.
- private function "_getGrowlNotificationDefaultOptions()" is the only undocumented (phpdoc) into Net_Growl_Application class.
- include script examples of real situation will be very appreciated
