R&D infrastructure creation using virtualization and simulation

How the virtualization can be used for research and development purpose across the corporate and enterprise by integrating it with other technologies? I would like to cover the integration of the virtual, real and simulated networks for research and development purpose of geographically spread organizations with diverse divisions. This will address the development of complex systems eliminating the bar of distance and skill set by developing the independent modules and integrating them. Also the purpose is to effectively use the underlying resources for research and development purposes so as to effectively control the costs associated with it. Today it is very common that research and development departments of big organizations are spread across the different geographical locations. Research and development in corporate also has become complex and large. It is no more restricted to just innovations, but also includes integrating different new innovations or new innovations with old applications. In this context it is very important that infrastructure exists that allows engineers in different location to innovate independently and then integrate them to solve some standard or known industry problem. This paper suggests a solution to such issue. Most importantly it does not cost much in today´s freeware environment to create this type of infrastructure.
