I've built a unix encrypting file system as a user-level loopback NFS server. Since the cost of the actual encryption dominates everything else, the horrible interface that NFS provides for a local file system isn;t as important as it would be for, say, a compression layer. A paper on CFS (the Cryptographic File System) will be presented at the Conference on Communications and Computing Security in November.
