OLPC Has Kill-Switch Theft Deterrent

Sid writes "Ars Technica reports that the One Laptop Per Child (OLPC) XO has an anti-theft daemon in the OS that can be used to remotely disable machines, much like WGA. The Project added the kill switch at the behest of a few countries concerned about laptop theft. From the report, 'OLPC has responded to such concerns by developing an anti-theft daemon that the project claims cannot be disabled, even by a user with root access. Participating countries can then provide identifying information such as a serial number to a given country's OLPC program oversight entity, which can then disable the devices in certain scenarios.'"

This isn't news...

Several people, myself included, specifically pointed this out during the last story on OLPC's BitFrost system..

And can we please remember that it's One Laptop Per Child, and not One Laptop Per Slashdot-reading Guerilla Geek? Any abuse regarding deactivation of the laptops is more likely to be carried out by confiscation of the laptop by school personal.

Also, the feature can be disabled with a Developer Key from OLPC:

1018 The anti-theft system cannot be bypassed as long as P_SF_CORE is enabled (and
1019 disabling it requires a developer key). This, in effect, means that a child is
1020 free to do any modification to her machine's userspace (by disabling P_SF_RUN
1021 without a developer key), but cannot change the running kernel without
1022 requesting the key. The key-issuing process incorporates a 14-day delay to
1023 allow for a slow theft report to percolate up through the system, and is only
1024 issued if the machine is not reported stolen at the end of that period of time.
