[IAEP] <OLPC

[Tony Anderson]

Hi,

Unfortunately this neat proposal doesn't address the Journal (nor my 
problem of delivering the correct educational content per the grade 
level of the user).

On balance, the risk of work being done by one user in the name of 
another is probably not worth the 'screensaver' strategy. In the end, 
the users will have to learn the habit of identifying themselves.

Tony
