That's a clever idea. Dan Reed has some code written that's a bit
simpler approach - it just rsyncs the homedir periodically.
The hard questions on homedir backup seem to be around how it interfaces
to an "industrial strength" backup solution, i.e. we can keep the
homedir synced to a network share pretty easily, but how does that
interact with incremental backups and so forth.
