Is there a way to get CSV-formatted output via a REST call?
We have a 3rd-party app that can import data periodically from a URL pointing to a CSV file, so the aim is to provide it with a Civi URL (probably going to a custom api function) that returns selected data as if it were just a plain CSV file.
EDIT: Civi 4.6.10 currently on WP moving to Drupal
