This project would not have succeeded without the assistance of others. I'd first like to thank Jason Thorpe for his advice and assistance with many of the kernel design issues raised in this work. My fellow NAStore developers, Tom Proett and Bill Ross, helped me devise how the kernel and NAStore programs interoperate. Harry Waddell and John Lekashman, our management team, encouraged and supported us during the entire development cycle. Finally I would like to thank Chris Demetriou for his design suggestions and especially for his review comments regarding this paper.
