That's a clever idea. Dan Reed has some code written that's a bit
simpler approach - it just rsyncs the homedir periodically.
The remote on-again-off-again network distributed file system is exactly
what CODA is designed for. And it handles laptops in disconnected mode,
caches files, and merges changes back in on reconnect. Lots of good
stuff in there, and many lessons learned. You may find slight
differences in your requirements but it deserves a close look because it
addresses most of the problems I have read about in this thread so far.
