Automated Multi-Marker Calibration

I'm currently working on a project that involves using a set of markers to 
register some global coordinate space.  I've been trying to lay out the 
markers and write the transformation matrices by hand, with limited 
success...As I was working on it today, I realized the ARToolkit could 
probably do a better job of calculating the transformation matrices than I 
can, and well an automated multi-marker calibration tool using the 
ARToolkit seems like an obvious next step.

Turns out a few people figured this out already, and presented such a
system at ISMAR last year in a paper called "Interactive multi-marker
calibration for augmented reality applications".  Does anyone know if this
system was ever made available?  I can't seem to find a web page or code
for the project.  Have other similar tools been developed that are
available?  It'd be nice to be able to use a well-developed tool instead
of reinventing the wheel.

Thanks,
