The problem with this approach is that unless you have a corporate blackberry you cant take advantage of that feature. Additionally, a lot of places I have seen won't accept "the camera is disabled".
I can't understand why RIM is approaching phones this way. The currently have the in with government phones as most government agencies are providing Verizon blackberries to their employees. It seems they are ignoring a large segment of their market share by not creating a new camera-less phone for Verizon. I would think Verizon would be pushing this as well.
