I can tell you we are using unencrypted OBB files that are quite large in size, so large that we had issues with the JOBB tool similar to those mentioned in several Stack Overflow posts (<stackoverflow_url>/questions/15832039/jobb-crash-fat-full). Sorry, my account has too few posts for direct outside links, so you'll have to add the URL there.
