Are there any kind of guidelines and limitations you have on the kinds of scripts that can run on the server? For example, are there ports you allow scripts to use, whether it be 80 for displaying web pages or other "random" ports for add-ons like those cross-server chat ones? Also on CPU (e.g. server locking itself for a few seconds consistently for calculations) or RAM (e.g. data stored in hundreds of thousands of objects)?
Of course, there are shallow limitations in Torque itself, but I don't know how you have things structured.
