I think it would be really cool if the Lightning.Pub accounting system (for users using shockwallet) was on top of a cashu mint and not only a pure LN node (neutrino). In this case you could have both the nostr real-time sync and connection to the node (instead of having to manage VPNs, Tor, etc...) and privacy for each user wrt the node operator, right? And maybe this could enable a "private cashu mint" where only whitelisted npubs could connect (family, friends, etc...).
