In a quick pointer from Ash this morning, "CloudStack is an Eclipse based plugable framework for building rich desktop applications that can be accessed over any web browser. CloudStack brings together the ubiquity of the web and the richness of the desktop - to create what we call peer to web applications. There has been a lot of interest lately in rich internet application (RIA) platforms like Apollo that let you build desktop applications that seamlessly integrate with the web. CloudStack goes further. Not only can you integrate the web into a CloudStack application but you can turn any desktop application into a web addressable application."
