You need to keep the same tangent in the points bellowing in the line. Check http://jsfiddle.net/FHKuf/4/.

Edit:

Sorry, just noticed your comment today. Just happened to be testing something related and remembered your question. It happens that in the past I did wrote some code to interpolate some lines. It is called Catmull-Rom(just a ref. that I googleed) it passes by the middle control points. I did changed the code to my test and thought that you may have some use to it. See at http://jsfiddle.net/FHKuf/6/.
