Another reason for the XSCE push was to make the server less
monolithic and allow deployments to select components. For instance,
Moodle is integral to XS 0.7. Most projects (to my understanding) use
the admin pages in Moodle (added to stock Moodle by OLPC) and not
Moodle itself. Most people on this list do not have a good exposure to
the continued use of Moodle in an institution (I use it at work every
day), so Moodle has failed to take root. In my opinion, for Moodle to
take root, it needs to come populated with sample courses and a set of
simple directions to add more. From what I gather, there are NO
instructions/documentation on the use of Moodle in the OLPC context.
This is most likely because we all hit the 24 hour limit per day :-)
Is it salvageable? Yes! We need a good set of courses and a repo to
host at and download from. A Youtube search for "moodle backup
restore" will show you how easy it is.
Moving along, XSCE hopes to provide a menu approach to select the
services you need (Pathagar, Drupal, <your favorite service>). That
requirement, along with AU's need to have a server per classroom (XO
based server) got mixed up in the granularity requirement.

As of now, this is true. XS 0.7 is rock solid, and it's stability
comes from the CentOS/RHEL underpinnings. Once XSCE is able to provide
a menu to "remove Moodle, add Pathagar" AND provide a CentOS base, the
reasons for XSCE may get stronger.
In case you were wondering, I am NOT a fan of using Fedora for a
server. Stability and upgrade paths are my primary concerns.
