Windows 7 to have support for Virtual Hard Disks

Windows super-sleuth Long Zheng keeps his eye on the Microsoft jobs listings and discovers some information about a potential new feature for the thus far super-secretive Windows 7 OS - native support for Virtual Hard Disks (VHDs):

Do you want to join the team that is bringing virtualization into the mainstream? In Windows 7, our team will be responsible for creating, mounting, performing I/O on, and dismounting VHDs (virtual hard disks) natively. Imagine being able to mount a VHD on any Windows machine, do some offline servicing and then boot from that same VHD. Or perhaps, taking an existing VHD you currently use within Virtual Server and boost performance by booting natively from it.

And so it goes on ...

If this feature actually survives to RTM (and let's face it, that's a very big if ... history is littered with great ideas that never saw light of day) then this will be a really neat feature. In fact, I can think of a good dozen situations where this feature would be dead handy right now.

Anyone want to take bets on whether this feature actually makes it to RTM?

Thoughts?
