In zaShunina's canon, one of the devices he brings with him is an object that allows people who see it to no longer require sleep (though they can still do so if they wish). He hasn't had this device in Prisma, but since all it requires to work is an image of it (since it works over television broadcast in canon), would showing an image of this device over the network be allowed? Obviously, how well it would work to actually keep people awake would be left up to individual players if so.
