Only project I have done this year (http://route.im), makes $xx/pm however doubt that it would ever cover the server costs, especially when more locations are added.
Although it was done more for me, than generating revenue, so that's not too bad.
You could do an Ookla like thing and create a mini version people can host. My server seems to be in the same place as yours, otherwise I wouldn't have minded hosting one.
