We present an architecture for a next-generation Internet based on Web Services and Utility Computing. This architecture would be realised as a series of open but interacting markets. We present a scenario whereby these markets could develop, driven by economic forces and market opportunities, exploiting technologies developed in e- Science and Grid computing. We argue that, if properly realised, such an architecture would provide a safer and more cost-effective way of supporting the Internet than the current infrastructure and would provide many opportunities for radical developments, affecting and unifying many areas of academia, business and society.
