Yes.  We are hoping to get one including some critical new
services (activation and update) out in the next week.

Focus on one of the first two.   I'm curious what you mean by  
"BitFrost", cause
the BitFrost document didn't really extend past the laptop.   The  
current ID scheme
(described in earlier mail to Martin) IS the BitFrost ID scheme.   A  
private/public
key pair is used to identify the student.   As this is kind of  
awkward for a username,
two derivatives are in use:  the laptop serial number and a hash of  
the public key.
This is probably changing somewhat in the future.

The network is the biggest headache right now.  Are you planning to
deploy in any schools larger than 150 students ?

Squid is working fine, although I'm not sure the logs get deleted as
well as rotated...    Update to the testing repository (edit /etc/ 
yum.repos.olpc.d/testing
and /etc/yum.repos.olpc.d/stable) --- make sure you get xs-config 2.5-8.
Restart the httpd server, and now you should be able to start and  
stop web caching with
/etc/sysconfig/olpc-scripts/TURN_SQUID_ON and TURN_SQUID_OFF.
These persist across reboots.

I'm working on getting Dansguardian packaged and configured.
