Chatbot communities are necessary for them to work together

[Late night reading about "chatbots" - emergent communities of software agents] Narwhal is a design tool for creating conversational interfaces. The whole topic of creating a community of interacting chatbots has gone un-noticed. I presume such a community will work in a way that enhances the total effect, with individual classes able to announce their capabilities to each other and, perhaps, some forms of emergent behavior. The development of environmental controls and of 'learning' features would be interesting challenges.
