I'm out of the office until next Thursday. If you can wait until then, I can give you an ellaborated opinion. Otherwise, I don't think we should drop the EpiphanProducer from the code but I agree with the opinion that the install scripts should be less Epiphan-oriented (in fact, they need some refactoring to make them more user-friendly).
