WuWu 0.94 (Windows)
Source: Interface Dynamics
From the developer: "WuWu is an incredible new group-based communication product that will change the way people use the Internet forever! Imagine being able to use one single interface to communicate with other people online using different methods like: instant messages, chat, file sharing, voting, and all sorts of other types of collaboration. WuWu uses 'Communication Modules' to do this which are simple to add and remove and they are completely separate from the application, which means that after the release people will be able to create their own custom communication modules using our moduleSDK."
