Re: Production Web Applications in Prolog

this is probably only slightly related to discussion, but its a nice curio.
I'm using Prolog as logic engine for bots in Counter-Strike (an FPS game),
the project is very experimental, but i'm running live online experiments,
so there is some "production" quality in it and its somehow related to web.
Project website is here: http://www.kappalabs.org/bti.html#en

... and to contribute something useful: i'm using EC2 Amazon Cloud, there's
totally no problem in installing Prolog.

Cheers,
Grzegorz Jaśkiewicz
