Sadly the Blender Conference don't offer a stream which can be watched everywhere by everyone. In Germany the Yotube stream is blocked - other countries might be affected as well. One would have to install a browser plugin to watch it in a non-legal way. If you do so you can only watch each presentation as a stand alone, so you have to open the next stream manually. That makes any parallel event useless, 'cause most people don't understand this concept and the event gets interrupted by ongoing questions on how to watch the stream. What a shame!
There were several visitors at the VWBC at the beginning, but they all left. Yesterday the stream of DeBalie was up, and it was running well, even in-world of Second Life. That would have been perfect - sadly it is offline now.
