Just a general thought, it seems like the OLPC security design is a real-world implementation of Bill Cheswick's "Windows OK" proposal. See for example http://usablesecurity.com/2005/07/07/bill-cheswick/ for more on this (modulo the comments on "feature starvation", which don't apply to the OLPC design).
