Lot to respond to, will do as time allows.
@eravsar, we've actually put a good amount of thought toward the % of tips idea. Bitcoiners that use the Fountain app have had tip splits for years. It's common for content creators there to specify 2-10 different recipients besides themselves and custom % for each.
For us to do that in a noncustodial way with Monero, we need to wait for Carrot, which launches with FCMP. XMRChat/XMRPod uses integrated addresses to link messages with detected payments. Today, you can't send to an integrated address and 1 or more primary / sub addresses in a single transaction. Carrot makes that possible.
Then we'd need wallets to add muti recipient URI support. After that, a fan can enter a superchat like usual. They scan the QR code to pay, and their wallet populates the send screen with multiple recipients and amounts with % as defined by the content creator. Fan confirms, and it's sent.
All that said, Split Tips is mainly a feature to make XMRChat/XMRPod more attractive to content creators. Unless tips ramp up like crazy, 2% will be dwarfed by revenue from ads.
Best case scenario is maybe this work will serve as an example that gets copied for other uses that helps Monero adoption. Maybe weekend farmer's markets or festivals will see it as a better way for vendors to pay for selling at an event, vs collecting fixed fees up front.
