It would be really nice if there were a way to get all the data that is displayed on the accounts tab of the Stack Exchange network profile for a user (e.g. [mine](http://stackexchange.com/users/ed3135bb-6f1d-487b-9930-85a7eb3a675b?tab=accounts)) as machine-readable data with a single request.  AFAIK, getting the badge counts requires making an API call to each site, so that getting the equivalent data for a user with accounts on *n* sites requires at least *n*+1 API calls.
