When I looked, that's all I could find also, other than shorter
summaries of the technology.

Here's a brief description:
http://www.altium.com/files/learningguides/WP0101%20Topological%20Autorouting.pdf

We currently use the previous generation, the rectilinear expansion
technique described in the above.

The Xplore paper I found was only $35.  That's a lot less than the
$100-$200 each for POSIX specs.
