Windows Intune, Microsoft's cloud-based PC management and security tool, is designed to remotely maintain Windows PCs and notebooks. But I'm starting to wonder if Microsoft (NASDAQ: MSFT) will gradually extend Windows Intune to support mobile device management (MDM) across Windows 8 tablets -- and yes, perhaps even Apple iPad (iOS) and Google Android devices.

Publicly, Microsoft has always stated that Windows Intune is a Windows-centric management platform. But privately, I know Microsoft has contemplated extending Windows Intune to support non-Windows devices.
