Reiserfs (version 3) doesn't support neither compression nor encryption.
It is supposed to be implemented in reiser4 for individual files (and 
maybe directories). Perhaps we'll develop a scenario when file system 
looks for a secret key in the key token of the process, inherited from 
its parent.

file system can perform encryption on suitable layer (in flush-and-commit
time), it means an advantage.
