A lot of the comments above strike me as the IT equivalent of King Canute - we don't like it so you can't have it. Well, if (and that is not yet certain) it makes economic sense for the business, then it's likely to happen, whether or not IT want it. There will be plenty of external consultancy firms telling the directors that they can do it, even if your "backwards IT guys" can't.
IT should be about finding how we can successfully, securely and efficiently embrace new ideas and technologies, not protect they way we do things now.
The tide comes in on it's own schedule, not ours.
