Julien Devade sends along the word that MASA has just released a new SDK middleware for Game AI. Here's a juicy bit from the site:

""DirectIA SDK provides developers with a cutting-edge generic toolkit that gives them the ability to generate agents and to integrate them in any software of their own.""

It sports features like hierarchical path-planning and translation of behaviour scripts as native C++ code, among many other things. Be sure to check out their web site (http://www.directia.com/) for more information.
