I believe you can functionally achieve that using loopback mounts of a file for each person and mounting each of these file systems in /home. This would require fixing the amount of space each person has available. The users would need to supply a password at some point after the system was rebooted, but you can make some way for them to do this before their home directory is available. You might be better off stepping back and doing a threat analysis though. What are you actually trying to stop? For example the system administrator will be able to access all of these files if he records the password used when mounting the encrypted file systems. If you are trying to protect users from third parties who steal the hardware, then having one password for the partition /home is on should be good enough. Users can protect files from each other using normal unix access modes. In FC5, SELinux will give a way for the system administrator to enforce this more rigorously using multicategory security (if the number of users isn't too large).
