[rules-dev] drools and google app engine

I saw an earlier post where someone ran into file access issues deploying the Drools engine on Google's platform. It seems like a relatively simple task to overcome this with an aspect and a weave. But before I attempt it, I was curious if anyone had managed to get Drools running in the app engine environment? If so, was that the only issue encountered and what was the level of effort? I was thinking it might be a fun learning exercise to leverage GAE and CEP in the creation of Google Wave Robots. I know, I have too much time on my hands. cheers, -Jess
