Re: VMWare flash future
VMware already has its own OS. It's called VMkernel, and it's what ESXi runs on. Hell, it's even binary compatible with Linux (and judging from current GPL lawsuit includes a chunk of code from it as well). And ESXi can supposedly virtualize itself, so nothing except the minor issues of usefulness and sanity stops you from running your services in a VMware OS inside a VMware VM inside a ...
("Bare metal hypervisor" is, by the way, a stupid marketing term that doesn't make sense on anything remotely resembling this kind of virtualization. No matter what you do, you are still gonna need memory management, scheduler, drivers, etc. - the makings of an OS. And in VMware's case you literally have a general-purpose OS with a standard kernel architecture etc. - just one that's optimized for running specific applications)
