Although there are consistency issues there. Coda provides essentially the same service as it caches on disk in its Vice Cache, but may be more aware of the consistency constraints. We're still investigating the possibilities of Network Computers and Coda -- it seems like one could almost just have a kernel + boot utils and a large cache, and live ones entire life that way. Many machines at CMU already pull most of their local/ binaries out of AFS. With AFS, new executions start blocking as they can't contact the server, but with disconnected operation in Coda, NC's make a lot of sense. I'll be looking at porting the RPC2 package Coda relies on to Java sometime in the next few months -- having access in Java might be pretty useful.
