Yeah; but the biggest problem you'll encounter in launching this is that you're not Microsoft. Microsoft has an extensive partner sales network and a lot of companies already using many of its infrastructure products. They write the SDKs and IDEs that developers use to develop Windows apps. They write the software that the system admins run on the servers. They write the security policy management systems that most companies use to manage their users, applications and hardware. And they also write the most popular desktop applications so they can show people how to really implement something like this.

I don't think anyone other than Microsoft can realistically do this. Which is exactly why Microsoft should; it's a product that nobody could copy and they would have a 90% market share on corporate BYOD management in under 5 years. Nadella is the right guy to actually push something like that forward; I just hope that the shiny consumer stuff doesn't remain a distraction. There's nothing fundamentally cannibalistic about someone running MS Outlook on their iPad: in order to do this, they still need a Windows user license, an Exchange license and an Outlook license, so MS is still getting paid three times for that user.
