I would be fully in favour of a system like this. I've said about putting ads on peakd dozens of times.
Earn revenue, buy hive from the market and either burn or distribute to staked hive holders. It could be thousands of dollars a month bought off the markets and put into the hands of long term holders. Drive up the price and increase interest in the token.
Same applies for splinterlands and would be a great way to put some buy pressure on SPS. I would include an option to turn off ads and not earn revenue or for people with over a certain amount staked as some people hate ads.
I think it's a tough sell though as a lot of the developers are very against ads and think it takes away from the product instead of seeing the benefits of an extra revenue stream.
