Network Wide Points
A network wide functionality of points on the points an rewards plugin would be nice. This would enable a cooperation that is operating multiple brands, under multiple urls and multiple store fronts to share rewards points between their businesses. Also having a way to bridge the gap between online rewards and providing some type of card reader application for in store rewards would also be awesome.
I'd also like to see this feature. In my case the use-case is a single brand that has stores different countries/regions that they serve. Since user accounts and details are already shared on a multisite network, it makes sense that a user's reward points would also be available across each region,
