Paying for short-term stays at an OpenVillage house in PayCoupons
We have briefly thought about this here, but then discarded the idea. This means the "Booked Scheduler" software recommended above is immediately usable for Reef booking, as it does not need any kind of payment integration then (and renting out the same room via AirBnB can be done in parallel).
The reason PayCoupons is not the right tool for short-term "moneyless" room renting or other spontaneous purchases is: you have to wait for PayCoupons network barter transactions to happen. This conflicts with wanting to book the room "right now".
There are two possible workarounds for this:
Saving up in PayCoupons before needing the room. But, visiting cities is a rare and unplannable activity so it would only make sense if you can use the same coupons in a network of at least 30, better 100 cities across a region like Europe. The Reef network may provide that eventually, but certainly not right now.
Paying in own coupons rather than coupons of the space. This is always possible, as everyone can create own coupons as much as they like. It is however not the idea in PayCoupons, because it places too much of the risk on the seller: the space-operating organization will not know whether they are ever able to utilize these coupons (by redeeming or exchanging them). One might argue that unused rooms are excess capacity, so it does not hurt to sell it for unredeemable coupons. That is true when introducing a rule that those paying in money or coupons of the house have priority access (cancelling other bookings until 24 hours before the stay). Such a rule is allowed within the PayCoupons economic system, so why not.
That second proposal may work in our case, but it's certainly not an economically attractive option for general use, and thus not an attractive option for introducing PayCoupons to mass adoption. Even for ourselves, it may not feel right to make hosting Edgeryders community members a transactional relation – only when we have so many guest rooms that all kinds of people stay there, it would feel appropriate. For the moment, I'll put the idea at rest.
That said, I'm up for installing Booked Scheduler for The Reef Brussels if you want it as an automated booking calendar (without any payment integration).
