The protocol means that RIM doesn't have the keys for mail sent over
enterprise RIM systems (unless it's the pin-to-pin messages, which as
someone else mentioned, have the same key installed on every device. I think
medium-paranoid companies can change the key globally -- but it's still on
all of their extremely devices).

Of course, RIM *could* build a back door into their software (or their
devices) to bypass all of the enterprise protocol's carefully tended
security. But one whiff of that and all the businesses and governments that
were lary of using RIM in the first place because of their external
management of the BlackBerry infrastructure would run screaming.

Anyway, this is different from the consumer BB offering.
