Me too ;). I'm not sure if cipux or lwat or some other tools might be
used. It will depend on how much work is put on those tools.

That's really easy to do: download from rom-o-matic a booting image
acccording to your network card, and add it to the grub menu of your
disk. i.e.: add a new grub entry with:
Title booting from the net
root (hd0,0)
kernel /boot/the_image_you downloaded

That's all: grub will start and will let you choose between booting from
the net or from the hard disk. Anyway that's something Debian edu can
not assign as the default behaviour, as the "thin" client require a hard
disk to boot.

I'm afraid I don't understand what you mean here. I don't know linbo.

ocs client configuration is in the setup for the Lenny based future
Debian Edu release. The server for ocs is not done and I'm afraid it
won't be done because the package does not support debconf to be
configurated, so it must be configurated manually.

No idea about italc, I'm using controlaula that's being included in
lenny too. The requirements to work out of the box is including the
teachers in the teachers group.

same as for 5): controlaula allows the teacher share/unshare printers
and enable/disabling internet individually or for the whole classroom.

I haven't tested rosegarden, but flash can not work out of the box as
Adobe doesn't allow including the plugin in the cd or dvd. Anyway, after
installing flashplugin-nonfree, it works perfectly. I'm afraid we can
not do much on this field: that's what usually happens when you use
propietary tools.

In the past I've just symlinked $HOME/.wine to /usr/share/wine and
installed apps for all users in /usr/share/wine. But that's something
you only can do if you're sure the users will accept that someone else
installs the applications for them. Doing that way the user can not do
it himself. You need to choose: freedom and individuality, or

In the Lenny Debian edu release:
install education-menus and put your users in the teachers or students
groups: you'll get a much better menus structure: exactly what you're
asking here

you can do it using acl's in squid.

yes, but in that case we'd need to think much better the interface of
such tool to admin so many different things

As you can see, some of the things you're asking have already been done
for Lenny. Some others can not be done generally for everybody,  but you
can set them up easily, and for the rest I'd like to hear more opinions
and ideas about how to do them. I think nobody will oppose to them as
they seem to be nice improvements for our distribution.
