The Eclipse community is very good at enabling innovation networks. Eclipse provides the ability for individuals and groups to create collaborative communities that drive innovation in a specific area. CDT is a great example but another up and coming project that appears to have an interesting community of committers is g-Eclipse.
g-Eclipse is trying to solve the problem of making grid computing more accessible to developers. To make this happen a consortium of universities and companies are collaborating on the development of some pretty interesting tools to access computation grids. Eclipse is providing not only the technology platform but the IT infrastructure, IP sharing framework and development process that make it possible to quickly create innovative new solutions.
