  Round table discussions are in the tradition of ACAT. This year's plenary
round table discussion was devoted to questions related to the use of
scientific software in High Energy Physics and beyond. The 90 minutes of
discussion were lively, and quite a lot of diverse opinions were spelled out.
Although the discussion was, in part, controversial, the participants agreed
unanimously on several basic issues in software sharing: (i) The importance of
having various licensing models in academic research; (ii) The basic value of
proper recognition and attribution of intellectual property, including
scientific software; (iii) The user respect for the conditions of use,
including licence statements, as formulated by the author. The need of a
similar discussion on the issues of data sharing was emphasized and it was
recommended to cover this subject at the conference round table discussion of
next ACAT. In this contribution, we summarise selected topics that were covered
in the introductory talks and in the following discussion.
