How to access current values from a Chef data bag?

I have a server managed by Chef. I need to access some values that live in a cookbook data bag from scripts not run by Chef.

/* Chef REST API allows to access data bag values as seen by Chef server. This is not what I want. Each chef-client run may introduce a number of coordinated changes, including changes in the data bag. If data on the server had already changed but chef-client did not run locally yet, local setup and server-side data bag may be out of sync. */

I see two solutions:

Are there better options?

Dumping data from the node hash or data bags into a separate file is a good way of communicating between the Chef server and scripts running on a node. If your script can parse JSON then it's really easy:

file "/etc/script.json" do
  owner "root"
  group "root"
  mode 0644
  content node[:whatever].to_json
 end

Using the Chef REST interface sounds like overkill, and groping around in /var/cache/chef is just rude. (-:
