A remote LND instance can be a funding source? The only version I know of that uses an existing LND node as a funding source is by installing nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm Hub on your Start9 or Umbrel node, but in that case it would be using the local LND instance as the funding source, not a remote one.
