Hi,
Since I have a lot of text-warping ahead in my future, I wrote a little script that greatly exdedites the process of warping text. There are many improvements that can be made, however it should give you a good start.

There are more Blender-oriented Python scripts available on my site, be sure to check 'em out.
Comments are always welcome. The code is GPL. However, if you make any changes (like adding a user interface, for example), you are strongly encouraged to post your modifications.
