You might try to try sending zaps over NWC, paid by ecash held in your wallet (requires push notifications working).
Or you might send ecash to any nostr address (minibits addresses work as both nostr and lightning addresses)
You can add another minibits user to your contact list and then lock ecash token to his wallet before sending - such token can be even published freely over nostr w/o being claimed by bots in seconds.
