But I don't think it's impossible, especially if you're working under the assumption that the user isn't allowed to touch anything. 'make world' can be construed as a small step in the direction of automated upgrades... A halfway solution might be a workstation connected to application and data servers, where applications and shared (non-user-modifiable) data are cached locally. Every time you request a remote file, the system queries the server for an MD5 or similar checksum and compares it to a locally stored checksum of the cached copy. (this almost sounds like Coda FS...) In any case, I don't see the point of an NC as a separate platform. As far as I am aware, everything an NC is supposed to do can be implemented in software on existing platforms using existing operating systems (possibly with hacked kernels). The pretty blue (or black, or whatever) box and the cool name are just marketing fads. "FreeBSD workstation running custom software for automatic upgrades" doesn't sound as cool in a TV ad as "International Gizmos, Inc.'s hot new Network Computer" DES -- Dag-Erling Smørgrav - dag-erli@ifi.uio.no To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
