Icarus, the video tracking, distortion correction, and reconstruction programs (which are freeware, non-comercially) are now available for Linux (i686), SGI Irix 6.5 (IP32), and Mac OSX on top of the original Windows versions!

But the best part is that Eeshlo created an import script so that you could use the camera tracking data in Blender!!
