Thanks, that's a great idea and something we are considering as well. It would be nice if we could make money off of premium features but the ad-sharing would let us at least pay the bandwidth costs.
I agree more with nl who posted above. Run ads on all sites by default, no rev split then charge users to remove ads.
A former company of mine did this. Many users hate ads on their personal sites and will gladly pay a reasonable amount to have them removed. Many also have no interest in making money off their sites. Besides doing a rev share complicates things a lot more.
