For a gem, i'm writing, I want to be able to access current_user (most auth systems have this helper)

What are some ways of doing that?

the thing that the controller includes to get current_user is this AuthenticatedSystem not sure how the helpers get access to it's contents

*I'm using RestfulAuth

If your gem has modules that get included on controllers, you can test if the method is available:

self.respond_to?( :current_user )

And if it is just call it. If your gem really needs it it would even raise an error if the method is not available.
