Manip, why not just use KiXtart? It's MS 'supported', it's command line, and it's very powerful. You have access to all of the COM stuff, as well as KiX's internal engine and all of the local machine and network settings.

It comes with the NT4 Option Pack, but is also freely downloadable at kixtart.org.

I really don't see any need for a command prompt or shell scripting language beyond that. I don't see what void it fills, who would buy it (and therefore how it'd get approved) or what problem it solves.
