A while ago I realized that spontaneous payments (without proof of
payment, mostly for donations only) can be realized quite easily if the
payer generates the preimage and hash, and includes the preimage in the
sphinx message to the payee node. If the payee node recognizes the
sphinx message format, it can use the preimage to claim the payment.
