Again: how is this different from LNVPN?? Customer: hits Buy Provider: pay this invoice (could be anything:LN, Monero, eCash) Customer: sends funds Provider: detects funds Provider: generates connection details & sends to customer

You can do that and it's already a great step up. However: - the payment is always associated with the purchase - as soon as you want to have a balance that can be topped up, you need user (accounts)

Can they do the initial buy with fiat?
