If you head to http://dev.laptop.org/git/projects/olpc-update/ -
you'll see a string of updates, as follows:

 - It now accepts sig02 formatted leases (based on dsd's patch, adding
sig02 support).

 - It will set the RTC if the OAT server gives us a signed time, and
our RTC differs by more than a day. (For smaller deltas NTP is boss.)

 - We now query a list of OAT servers - by default it will try
'schoolserver' and 'antitheft.laptop.org'.

 - The file /security/oat-server overrides the 'antitheft.laptop.org'
entry, so a local team can say 'antitheft.ceibal.gob.uy' for example.

 - If the OAT server says 'stolen' (always in a properly signed
message), the laptop removes any lease keys it may have and halts. It
won't remove /security/develop.sig so if you have a developer key, it
doesn't actually affect you.

These are major changes -- reviews welcome.
