according to Peter: "Version 0.3 is a complete rewrite of the Avanti code base after a rethinking of the basic architecture and design. The result is the beginnings of a simple, highly modular and scalable client/server architecture using its own native messaging protocol for client/server communication." For more, see the Avanti site [1] or you can telnet to the live demo [2] to try it out.
