[rules-users] Is there a faster way of doing this in Drools ?

thanks again everyone ! I think I've enough information at this point to do
some more prototypes to actually get a better idea of all the important
things people have shared in this post. 

I'm sure I'll have more "implementation" or "drools" specific questions once
I start exploring a little more.
