VMware's Virtual Data Center OS pitch not credible?

My quick analysis:

When you want to encapsulate everything in your data center in one box and call it "VDC-OS", it is wither a great ambition or a fool's dream.

Why a great ambition?

Maritz passed us both by, though, by declaring not only that VMware would continue as the high-end virtualization vendor of choice, but that the entire IT ecosystem was evolving past its dependence on the operating system into a kind of mesh world in which applications, data, servers and security are all handled behind the scenes and IT departments would have godlike powers of integration and management based on cloud computing, virtualization and a firm reliance on VMware management technology.

That's a bold claim no matter how often it's been made (by Novell, IBM, Microsoft, HP and others, under various buzzwords and in various guises over the years). Microsoft, in fact, is making the same claim again (though its recent PR-fest was, if anything, less credible than VMware's).

VMware will replace the current patchwork of desktop, handheld and server operating systems -- not to mention the variety of management, integration, DR and backup software that keeps most current data centers running -- with the Virtual Data Center Operating System.

The VDC OS will function as a kind of internal-cloud computing model, Maritz says, allowing users to access data from anywhere, with anything, and virtualizing applications, data, hardware, software, storage and, presumably, the vast supplies of coffee and pizza consumed by the army of IT people trying to make a VDC OS function.
