Here is the new Growl Display plugin that will send Growl notifications to an LCDproc server. This will allow you to view Growl notifications on any character LCD supported by LCDproc, or on any UNIX or linux terminal using the curses or text drivers. Because it uses LCDproc's TCP/IP connection protocol, you can send your notifications almost anywhere!
Using this plugin, I was able to forward my notifications to my wireless Zaurus PDA running in another room.
