In FAQ form:

q: What is this?
a: Something like this:
- two days conf with one day setup, which is like the conf, but more
  exciting;
- one large room, one small one, big hallway, maybe some rooms for
  discussions;
- participants chose of they would want to do streaming/etc. of the
  large room and we accommodate as many setups as possible;
- same for the small room;
- the talks are spaced by 1h each, so in the mean time people can do
  testing of the different setups and discuss them;
- the talks get chosen from some committee, and are either 1) what a
  conference is doing, 2) this new great thing that will make our lives
  easier, 3) something everyone does wrong and how to fix it.
- there is a single track. The small room is for tests only.
- probably up to 100 people. Hopefully more.

streaming, video recordings and all similar crap.
