As you may know, WinRM and WMI are implementations of public standards -- WMI is our implementation of CIM, and WinRM is our implementation of the WS-Management protocol. These are both published by the Distributed Management Task Force (DMTF), a consortium of 160 companies and organizations that develops and promotes standards for systems management. You can read more about them at http://www.dmtf.org/about.
The world of standards development can b a strange and confusing one. If you want to learn more about the DMTF, what they produce, and how they're organized, there's a great tutorial hosted by WBEM Solutions that explains it clearly: http://www.wbemsolutions.com/tutorials/DMTF.
