color:windowtext'>Drools supports a simulated clock (unified for rules and
processes), so this should allow you to build a simulator. The code that
Mark is referring to is just something built on top that allows you to define a
simulation as a sequence of commands that are sent to the session at specific
time points etc. You could try to reuse this as is if it would be useful
in your case, or simply try to do something similar. In any case, there
shouldn't be any technical difficulties that should prevent you from doing
something like you described I think (just not all out-of-the-box).</span><span

<p class=MsoNormal style='margin-bottom:12.0pt'>I have something prototyped and
it works, but I need to refactor the api and make it much simpler. so if you
use it, expect it to change a lot and get a lot simpler and better :)<br>
