Hey this is totally different approach: What if each user's home
directory was an encrypted file (mounted as a local loopback).  These
are laptops usually- for the need of occasional sync, so why not also
encrypt them also in case of theft, secrets, etc.

Then as an option at login you can answer yes/no if you would like
your profile (encrypted file) sync'ed before login.  Then the rdiff
does a compare against one (albeit large) file remotely.

Bonuses: encrypted, safe from losing laptop/local computer, at time of
login- exactly the same profile/home directory

Drawbacks: slow?, container size of encrypted file, version control
management difficult?

Just a thought!
