The second day of the workshop was almost entirely devoted to round-table discussions, which involved all the participants in an open exchange of their respective experiences, opinions and suggestions. The discussions had been planned by the organizers to be focused around 4 main topics, with designated moderators that also provided a few points as seeds for the discussions. However, the format was left intentionally free. As a result, it is not possible to present here an accurate and detailed account of all the discussions. We present instead informal summaries compiled by the organizers. The results of the round-table sessions were very positive, and this part of the workshop was appreciated by many of the participants. In the end, the discussions were so intense that no time was left for the last topic!
