[OLPC Security] Chilling effects?

[Mark Miller]

I notice at <http://www.usenix.org/events/upsec08/tech/tech.html> the paper:

Freezing More Than Bits: Chilling Effects of the OLPC XO Security Model
Meredith L. Patterson, University of Iowa; Len Sassaman and David
Chaum, Katholieke Universiteit Leuven

Is this the David Chaum? Anyone here know what chilling effects
they're thinking of?
