This can be done relatively easily with the current svn version of matplotlib (r8319). Below is the modified version of your code.
See http://matplotlib.sourceforge.net/trunk-docs/users/annotations_guide.html#using-complex-coordinate-with-annotation for how the annotation works. While this is certainly possible with the released version, but it will require you to write a few tens of lines of code. Basically, you need create a custom Text class that update its position during the drawing time.
