Hi Torsten,
Do bring a friend, this is going to be interesting!
It surely's gonna be! :)
Make sure to ask the panelists about the challenges to run a successful Free Software business without making the product non free.
See https://owncloud.com/products/enterprise/ at the end of the page for example.
Indeed! Luckily, I represent the other part of the spectrum, as I work for a company which will never deliver anything to any customer under a non-free license, and has had this principle since 1999. Indeed, we might compete with ownCloud Enterprise by offering SLAs for installations of the free version - we don't deliver ownCloud for the moment, but we do so e.g. with Alfresco Community Edition.
But thanks a lot for your observation! :-)
