The main blocker was being able to forward sats to Geyser projects' ln address (e.g. project@geyser.fund) directly, which SN still is not allowing you to FW to wallets outside of SN.
So we'd have to either
  1. hack it by receiving sats in Geyser SN wallet and then sending out the sats to the project,
  2. SN could allow funds to flow to @geyser.fund ln addresses.
