It was always a good tradition of T3BOARD, that there were people doing sessions in the evening. Either some cool features got coded together or someone presented a solution to a particular problem.
For T3BOARD20 we will have a room for our sessions, made available by the hotel. There will be a silver screen available (I will bring one, or maybe one of you has a bigger one).
There will also be a dedicated 'session-beamer' for your purpose, as usual.
Session planning will be held during dinner (or directly after) in barcamp style.
Sometimes, werewolves could appear after the sessions ... ;)
