Appreciate the thoughtful post. To do what you're asking for properly, the system would have to be backed by official dedicated servers. As you can imagine, it isn't cheap to rent solid, DDoS-protected servers all over the world, which makes it economically infeasible for us to do (we're talking thousands of $ per month).
Unless someone with deep pockets would be up for sponsoring this, our only option would be a peer-to-peer system, which leaves a lot to be desired...
