I' ve got questions about a business using LN.. So the owner needs to open a payment chanel with someone. Could it just be a customer? Are there Node runners who advertise for businesses to work with them? I suppose the owner doesn't need to operate his own node or need inbound liquidity if he's not sending through transactions? Then the other question. At closing time, you'd need to close the payment chanel, if you want your profits in your pocket, right? Seems saving credit card fees the business is charged could be a pretty good incentive to use LN
