Barjohn, The above statement is so correct. It even applys to airport security. If your carryon is searched and, for example, take away a lighter, you can walk into a book store in the secure area and repurchase a lighter. I needed a better example then lighter, but couldn't remember my co-workers true story about what they took away from her.
Anyway, this is an incredibly interesting thread. We are basically talking about the ability to use expanded memory on a Blackberry through an expansion slot, and many comments have been made about trying to secure the data through encryption.
The fact is, Blackberries have unlimited memory. The memory can simply be in the form of a client/server program that a berry stores and retrieves data. With data speeds increasing. RIM WANTS you to use the data network to retrieve and send data. This is what drives the carriers to offer products in the first place; the profit model involving charging for usage.
If the data on the removable memory card will be encrypted and used ONLY on that one blackberry, then the memory card is not necessary, it's kind of redundant. Write a program for the blackberry that stores information on a server, accessible only by that berry. Same thing, and more possible with today's Blackberry features at our fingertips. When are you NOT in coverage these days?
Whether using a memory card, or "online memory", one thing the Berry lacks out of the box, is a navigatable file directory. Dynoplex created their own, and the native picture application stores pictures in a file structure, but there isn't a native one you can navigate. Until there is, using any type of external memory is going to require applications to move the data around.
