I think that the better solution is to extend the nginx upstream module 
so that the list of backend servers (address, port and weight) can be 
obtained at request runtime, and not only at configuration time.

This means that a module should only implement the logic to obtain the 
backends list, and all the work can be done by Nginx.

However this assumes that on every backend, the URI to the file is the 
same (but this should not be a problem, if Nginx is on each node).
