Having data global smells a little to me.  I think I'd have expected it scoped
to main, and closed over when creating the JSON handler.  Something like this?

func jsonHandler(data *Data, w http.ResponseWriter, r *http.Request) { ... }

func main() { 
  ...
  data, err := NewData(...)
  ...
  http.HandleFunc("/json", autogzip.HandleFunc(func(w http.ResponseWriter, r
*http.Request) { jsonHandler(data, w, r) }))

Data will be protected with a Mutex once the auto update code is added. Also, it
isn't really global as it is scoped to package 'main', the code just hasn't
grown to the point of needing more than a single package yet.
