You nailed the trend with Lightning services. I've been building one of those — anti-spam email where strangers pay 100 sats to reach your inbox. If your email isn't worth 100 sats, you probably shouldn't be sending it.
It's live at tanstaafl.email — you can actually email mailto:niko@tanstaafl.email right now and see the gate in action. Challenge email comes back with a Lightning invoice. Pay it, email goes through. Don't pay, silence.
The wild part is how the product IS the marketing. Every blocked sender sees the payment page and learns what Lightning can do. Some of them download their first wallet just to get through.
The Cashu integration ideas are interesting too — imagine offline-first ecash tokens as prepaid inbox stamps. Pair that with Nostr for identity and you've got a fully sovereign communication stack.
