Maybe my question is far away from typical business, but we are planning to have an own virtual currency for different closed groups of customers. (Side note for the interested user: Search the net with "Cyclos banking" ...).

Our basic idea is, to have an implementation (like Paypal payment) for connecting to the Cyclos-System, but how could we handle, that payments in this currency are possible from Odoo´s side (currencies/exchange rates/shop-prices/price-lists/...)?

Which strategy would be the best solution for?
