ASP and Sender can co-operate to sign-off a VTXO without having to join a round, delegating (future) claiming rights to the Receiver. This VTXO is kinda of trusted, as the ASP can double-spend it, but the tradeoff is that Receiver can always join a round or prove to the world ASP cheated, hence will make all other user to unroll exiting the Ark.
Benefits are postponing liquidity allocation, ideally does not make the necessity of fast rounds and remove the need for the sender to interactively join a round to send a VTXO inside the Ark.
