Title: The help you requested... perhaps :)

Parses JSON via Python (not great, but no additional helper-app needed)
Uses 'on idle' vs 'while true' for less CPU usage
Default expected app is "Messages" but that can be easily changed via
the AppleScript Editor (I couldn't compile it using iChat because I'm on
Mountain Lion)
