I'm not entirely convinced that the private-public information issues in dtkeden have been properly resolved, so be prepared for some confusions/difficulties here. You would be doing us all a great favour if you can get to understand how dtkeden can be used most effectively, and whether there are some problematic aspects that need further investigation before you can do all you would like in that respect.
Another game worth looking at (though as yet not in a distributed form) is the Great Game of Britain, as implemented by Simon Yung and many of the MSc students somewhere around 1996 I believe (see ~wmb/public/projects/games/GGB).
You've obviously got some interesting things to consider in the modelling and the subject area: good to reflect more on where the specific focus will lie in coming up with a strong theme for the paper (which may emerge in time).
