The most appealing aspect here I think is the simplicity that Mesh can bring to these scenarios of multiple devices and people sharing data, and this leads to savings in development costs and user training and support. Most of the demos currently focus on the consumer space , but businesses value sharing information too of course, and I can imagine that this will become a compelling way to build mobile apps in the future, providing that the security is proven. I can see uses for it now, even in it's current form.
