@Turdicus @Paultron @doctorsex Just set it as a subscription model. Maintenance is sponsored by some company. They can sponsor one at a time or to into a generic pool. The headstone has an integrated OLED that can constantly change as new advertisers join the pool. You can leave virtual flowers by sending crypto tokens ($ReaperCash) to the QR code on the gravestone. When you visit a grave to pay respects, motion sensors will start to play an ad like when you're pumping gas. Think of all of this untapped revenue!
