thats why i wrote 
http://wiki.edubuntu.org/EdubuntuInstallNotes
the install isnt yet what it should be, the next release will be cleaner
there and generate the /etc/ltsp/dhcpd.conf file automatically...
that you have to give an IP address is caused by the fact that i must
assume there is no (and should be no) dhcp server around in a standalone
non networked classroom...(which was the target for our first release)
http://wiki.edubuntu.org/EdubuntuWiring
has some overview...

the next release will target a whole school environment so two network
cards will be supported by default, sorry for the inconvenience, but the
gui tools in the desktop dont make it to hard to set up a second NIC i
think.

absolutely... sadly my themed version didnt make it before the feature
freeze, so i couldnt get it into this release... i have an alpha version
(with no guarantees indeed) on http://people.ubuntu.com/~ogra/edubuntu/
follow the notes in ldm_installation.txt might or might not work....
(works here, but again, no guarantees and its not completely done yet,
you might experience bugs)

the gui tool for managing users offers a hand full of profiles and
creates the home directories accordingly...

that should be a part of TeachersPet the basic development just started,
we will spec it out more detailed at our conference end of this month in
Montreal...

thats the reason why we didnt include it yet :) i hope to get the
developers to fix up stuff for us before the next release, i'd love to
make it a default tool.

i admit the boot of the clients is very slow we'll work on it for the
upcoming release, but for example the ntp daemon never gets started so
it wouldnt slow down the boot, it only takes some small amount of space
on the server...

we wont change the setup of the CD, many countries have no fast internet
connection and cant afford DVD drives/writers, so the CD will always be
there and contain the smallest set of software you need to install a
classroom server...
you probably should have downloaded the DVD that contains everything in
ubuntus/edubuntus main archive...
http://cdimage.ubuntu.com/edubuntu/releases/breezy/release/
note that the terminal server uses default packages from the archive,
the ltsp packages themselves are only some KB big (thats one of the
biggest innovations (beside using ssh instead of insecure X connections)
in our new ltsp implementation)

thanks for using it ;)

i'll add it to the list for consideration :)
