One thing that can help with responsibility is to do a final pass at the end of the meeting and call out action items, including these near the top of the document.
The problem, I experience, is not that action items are missing. The point is that you must write the name of the responsible person next to each action item. Maybe even her email, so people can nag her. If possible, set deadlines.
However, the problem seems to be an inherently social one. I cannot imagine any etherpad plugin or something to help with this.
