Free for small group discussions. Some long-term participants may be approached to contribute to an industry briefing session in the afternoon.

The programme is flexible, especially with respect to discussion sessions - please let me know if you would like to show something at the sessions identified or if you want to propose other topics. There is room towards the end of the second week for more talks and discussion sessions as and when interesting topics arise.
