Habotat

Habotat is a small, lightweight application server for hosting IM services, more commonly known as bots. Bots are small, specialized programs that you can communicate with using an instant messenger (IM) client. They show up in your buddy list and are always there to do your bidding. A simple API is provided for the creation of new bots. The Habotat server supports run-time deployment, so bots can be loaded into the server, activated, rebuilt, and reloaded without requiring a server restart.
