Attempting to generate hypertext in local chat that, when clicked, would trigger the script to output more text to local chat. There's a viewer URI incantation that seems ideal for it: secondlife://app/chat/<channel>/<trigger_text> where the script listens on <channel> and responds when it sees <trigger_text>. Unfortunately in the Linden viewer (and Catznip), this results in "[Second Life: A SLurl was received from an untrusted browser and has been blocked for your security.]" after which it won't try again until a relog.
