I'd like to avoid a scenario where the mint is required to create a large number (millions?) of small (millisat) tokens or proofs
That's why I'm curious to learn about other approaches, which will likely need to be a bit more complex, to make this work with just a small number of proofs
I think we need the ability for the device to say something like "the router can have the tokens worth 32 sat, 8 sat, 1 sat, and 32 millisat", but where the router can delay the redemption until the device disconnects a few minutes/hours later
And we might need some sort of revocation login, where the device can "unlock" a different - likely overlapping - set of proofs while the router revokes its right to the first set
