Would be really cool, with LSP discovery via Nostr so there can be a real, transparent LSP market. Maybe with an API similar to phoenixd to have it compatible with lnbits etc directly from the beginning. But the fee credit thing will be hard to replace
It doesn't sound *that* hard to replace. I think fee credits are just a service agreement where Acinq holds custody of your sats until you accumulate enough to do a base layer transaction to open a new channel or enlarge an existing one. You could probably use ecash mints as a drop-in replacement: accumulate sats on an ecash mint until the user has enough to open or enlarge a channel, then do so.
