Definitely interested in using Distributed Charge technology for campgrounds. Although I'd like a dual metered trust-minimized micropayments based approach for energy and water delivery, I think that right now people are going to want to just make simple daily payments and leave some trust in the campground operator.

I'd be curious to know if the campground owners and customers are content with selling electrical energy at a fixed daily rate without metering or if they'd like some metering with periodic manual payments. Does anyone out there have an opinion on that?

I have a feeling that water is too cheap in most places that it won't make sense to include the metering system for it and just charge a fixed daily rate.

Will customers demand a partial refund for energy and water if they leave the campground early or will they be okay forfeiting that service? If so, I know of two ways that refunds can be done with lightning:

Which one of these would be preferred if they are necessary?

I have put something together called the Board A0 Relay Demonstrator. It can be used for doing simple switch control which doesn't require metering. I have not published much information on this, but in this workshop at TABconf I walk through using the hardware and creating a simple application from scratch that controls the switch : https://www.youtube.com/watch?v=jFZRJN7YbgQ . The Board A0 Relay Demonstrator is sitting on the floor of the stage to the left of the me.
