Nothing is prepared yet, but, if the topic of gaming AI is interesting to nixers, I can give a talk on what I worked on to improve unvanquished's AI, which are based on a bunch of technologies, including behavior trees, navmeshes and raytracing.

All won't stick in 15 min though, and attendees will have to suffer my french accent one more time. Also, I'm not really skilled on those, so I will only give introductions, the topic is yet to decide.
