Set iChat Status - Simple tool to set ichat status.
It's dead simple. Pick a status, enter a message, (or not) and click okay, or hit enter.
It's a .sitx file, so if your browser tries to download it as text, let it, save the file as text with a .sitx extension, and open it in Stuffit Expander, and Bob's Your Uncle.
Requirements : iChat 2.0 or greater.
