Make preseed/kickstart/unattended install possible

I'm in a team that deploy linux in large academic environnement. As of today, we're using essentially Debian because of the real ease of automated install : you can preseed the installer with even an http remote file ! There are others types of methods to do this, named kickstart or unattended. Even Microsoft Windows installer can be fully automated !

We'd like to deploy elementary OS, but we need that the installation can be fully automated. When you have just one person and one day to deploy 100 to 250 desktop computers for pupils, you can't seat in front of each computer : pxe boot, preseeded installation and voila !

The addition of this use case would be a real killer feature. Indeed for us it would be necessary :)

TIA for your consideration
