I didn't see AFS mentioned yet. My, admittedly incomplete, understanding of afs is that it provides a single namespace (directory tree) to all clients but the files themselves may be stored on a local or remote server; a bit like Microsoft DFS.
Standard AFS doesn't quite work like that; even if you're running on the fileserver (a bad idea) you're still going through the protocol (AFS filesystems are not directly accessible via *nix APIs) and the local disk cache, and you want anything like local speeds you need a cache large enough to hold the entire working set.
There *is* an experimental hostafs that enables individual workstations to share out their normal disk space in the way you're talking about, but I gather the code doesn't work with current versions of AFS. You could post a query to openafs-i...@openafs.org if you're desperate.
