My own presentation was fairly good. Someone came up with the question, how to trace changes within distributed objects. This question came up at every CONESYS presentation so far. My answer was that
1. it is a hard question
2. it could be done with a central CVS repository for example
3. it’s nothing you really want to do in a content network with lots of data
4. especially not in a peer-to-peer content network
5. and that the CONESYS DDO system simply transfers metadata about digital objects or the object itself containing files within a compressed archive.

Thanks to Heinrich that he let me stay at his place!
