The idea would be rentable or buyable drones that could display ads, or stream channels, or be programmed with a custom message by a decker. Not sure how it would work code-wise, maybe make it a function as a wearable item. Could also be expanded to be a rentable guide-bot, or carry stuff, etc. Maybe even be able to have tamagotchi- style interactions with other hover drones.
