This is a good idea, though it has been for a few years now. RIM expanding and leveraging there strengths and packaging it up as a service they could then not have to stress about bastardising the phones to be me-too's and also get a strong foot onto all other platforms.
Still sadly enough this is what will end up as, an app on the app market and then it will be done by whoever snaps them up at a bargin price. Would appear the board room is full of people busy coverig there own ass's and playing it so safe they have no grip on what to do as there busy doing the headless-chicken inside whilst trying to appear in control. But there again they knew he was probably be a going and so did he, hence he had the time to explore the more obvious routes of RIM's salvation. OSX may be great but how much have they sacraficed in moving egg's into that basket; More than they should of.
