The emulator is a tall order, though I will see if I can come up with a simple one that covers the use cases of the cache loader. The S3 library is about 30 or so classes, and separate is the loader which is like 2 or 3 classes. I don't want to bloat the cache distro with all that if possible. Will you be willing to help me with getting the S3 library built/deployed on the JBoss repository once the emulator is done?
