As you are planning to run 2 streams, perhaps making one technical/developer focussed and the other more general might help attract a wider audience. There are 2 other larg(ish) conferences at cebit - the eGovernment forum and the online marketing conference - both of which are good Drupal markets. Having a few government or online marketing focussed sessions would perhaps tie in well.
Evangelising Drupal
So do we get an opportunity to evangelise Drupal in session(s) on Tue/Wed/Thu that are open to CeBIT attendees? Or do we just have the stand and website competition to do that? Having someone speak at a session would be a fabulous opportunity to address a large cross section of the IT community.
Check out the program
Check out the recent post about the tentative program - that is more or less what we intend on doing. I welcome more feed back though.
Thanks,
