Might sound a bit harsh (and don't bite my head off for this) but I don't think there should be any livestreams, why should people get some of the con experience for free when those who attend pay hundreds?
If you have friends who can't attend, you can take pictures, record videos, and livestream yourself if you like. A lot of videos and photos get put online from cons anyway.
There's no need to put extra stress on the staff for this.
