Storm in a teacup will result in more bittorrent seeds... More seriously: my kids school are always using their smart whiteboards to play YouTube videos and DVDs on, particularly on pre-Xmas slacking week (the one that the teachers think everyone is entitled to in the UK). How does this fair with such terms? Would they sue a school?
