Not to sidetrack the conversation, but will BB Mobile Fusion (BBMF) be embedded in BB10?
I know that tendencies like Bring Your Own Device (BYOD) promotes these types of apps/features as optional.
I think that part of the security offer RIM brings to the table should be a non-negotiable: All Playbooks that need to be connected to a BES should be required to do so, and not be at the mercy of a user uninstalling the app if he disagrees with his company's policies.
