Can you describe how you envision pay-to-subscribe would would work? Pay to whom, subscribe to what/whom?

As for the reposts, our goal is to make all payments direct to the author/turf owner. There is no stake. We don't want to take custody of people's money. When you make a tip, it goes directly to the authors wallet. When you pay a turf posting fee, directly to the turf owner. So with onchain Monero transactions we would have to have users make multiple transactions in order to split payments, which is a no-go in terms of user experience. Batched transactions are only possible from your own wallet. Stasher can't construct a split payment and show you a QR because Stasher doesn't know which outputs are in your wallet, Monero protects that info.
