View that ignore node permissions?

I have a publishing site, where the majority of articles are public with a small subset only viewable by authenticated users.

I have a view that generates a custom RSS feed (password protected by server) which feeds the article content into an iOS app.

I realized that since this view is technically viewed as an anonymous user, the private articles are excluded.

I need a hopefully easy way to bypass access control in a particular view and show all nodes that meet the criteria irrespective of their permissions.

Any ideas?

Thanks very much
