Multiple Blackbeerries...what???

Some people have a tough time with the Blackberry as their work life never leaves them alone. Some people however enjoy the craziness....and then take it to the next level. The next level being a usage and carrying of multiple black berry devices. CRAZY!!! Here is an idea. On the server/computer side we have a capability to host multiple systems on one piece of hardware. We install multiple network cards and really one piece of hardware efficiently supports multiple systems. Translate this to the phone/blackberry world and I see a gizmo that will be one physical gizmo but will actually have multiple phone numbers in it, kind of like multiple phone line office phones. The gadget will allow the owner/user to maintain separate address books, separate calendars etc. In fact with each phone number that would be implemented by inserting a card or an ID of some kind or scanning a 2D barcode, the gadget would not only get the new phone # as well as setting up security on whether the address boook, calendar, e-mail etc. associated with this phone # can actually be shared within the device or not. This would allow a person to have several phone numbers and use a single phone book, but in case of a corporate/work stuff, the company could set it up so its information could not be copied within the gadget or added to either. Here is an idea...You heard it here first!
