Most laughable is the idea that VMware would have any reason to ask him to make Redis run on Windows. They make a lot of money off enabling easy deployment of diverse operating systems.
About that, VMware does a remarkably cool work to be fair with other companies (at the point I had problems understanding this behavior in the first months: in Europe competition is sensed always as something dangerous and I'm glad that VMware attitude is different), and in this specific instance I did not received any pressure about avoiding to support win32, actually I got some suggestion to be more open if the win32 port will become more reasonable/complete.
