Hi,
I've got a solution working with Samba, a cgi, an xmlrpc server, and
Zenity, so here goes..
http://gatopelao.org/2009/10/23
-Projects are a way of grouping drawings together under the same theme
or subject.
-Teachers can create and delete projects.
-Teachers can copy, move and delete drawings within the projects.
-All projects are available to all students.
-All students can create new drawings.
-All students can open any drawing and build upon it.
-Students cannot modify or delete drawings.
-Students cannot create or delete projects.
I posted it on the tuxpaint users list too. sorry if you got it twice.
Cheers,
Chris.
