Microsoft researchers have developed a prototype of a client-side architecture that would replace the Web browser with a much more secure virtualized environment that isolates Web applications. The architecture would provide a simple execution environment that would use only 30 functions in interacting with the client’s execution interface. Developers would be responsible for packaging their own libraries with their applications, a difficult process that in effect would hand security responsibilities to the developer. Microsoft described the architecture as a browser replacement, but also believed it could become a more secure alternative to desktop operating system apps.”]
