KDE kiosktool is what you are looking for.

kiosktool
Description: tool to configure the KDE kiosk framework
A Point&Click tool for system administrators to enable
KDE's KIOSK features or otherwise preconfigure KDE for
groups of users.

E.g. it is used by cosmopod.com to restrict the user desktop for their
nomachine accounts.

For a single classromm and not more than 20 pupils systems like
skolelinux,
RedHat K12 or edubuntu will cope your needs. I would recomend skolelinux
or
K12 because they offer a lot of 'automagically' predefined services as
user
accounts stored in ldap, centralised administration and others.

But for a more complex environment, eg. several classrooms and a lot of
users
you will see that they lack a lot of performance. This mostly because of
network limitations (not more than one subnet) and because of the use of
LTSP
which has a bigger bandwith footprint than nomachine/NX.

For such environment I would suggest a better scaling systems e.g.
OpenSchool
Server (OSS) [1] from EXTIS (OSS is the former SUSE OSS).
OSS offers a lot of predefined services, those offered by skolelinux, k12
plus
groupware, elearning environment and others.

It don't offer a preconfigured LTSP. But I don't see this as a
disadvantage,
IMHO it's more an advantqage...

I set up such a system with an nomachine service (wich is easy to set up)
As
thin-client systems I used thinstation [2]. Thinstation is a linux based
terminal client system which allows connections to nomachine, Cisco
Terminal
Services, MS Terminal Server and a lot others. So it is much more
flexible
than having LTSP only.

This system is serving a big vocational school /Berufsschule, BBS-II), 24
classrooms having 12 to 24 machines each. And it is serving more than 2500
user accounts in the moment. Every student has a personalized home
directory,
is able to use email, irc, web,... The system and all of its services can
be
used from inside the school and from outside the school, e.g. at home.

Plus a big set of squidgard rules for web access, which is a legal must
here
in germany to protect pupils.

Not to forget the use of kiosktool to configure/restrict the users
desktop.
The desktop predefinition/restriction is group based so that there is a
better
flexibility in giving more functionality over the years.

Is it possible to run LTSP if the Kiosks were wireless?
