I suppose some of the technical difficulties are unavoidable. I have to assume the technology is pretty complicated. But the problems range from audio and video randomly cutting out, to Octoshape's viewing slots being filled by too many users. This is a little surprising, since Octoshape had good performance for Blizzcon and even GotFrag. Just as frustrating, the Octoshape web site doesn't have any information about what was going wrong.
On the other hand, since Tom Chilton stepped off stage, the stream has been a lot more reliable. They've either fixed the problems, or the number of viewers has stepped down since the WoW discussion has ended. Here's hoping the better performance lasts.
