* TODO list: (items bunched together depend on each other)
*
* - Implement the service control manager (in rpcss) to keep track
* of registered class objects: ISCM::ServerRegisterClsid et al
* - Implement the OXID resolver so we don't need magic endpoint names for
* clients and servers to meet up
*
* - Call IMessageFilter functions.
*
* - Make all ole interface marshaling use NDR to be wire compatible with
* native DCOM
* - Use & interpret ORPCTHIS & ORPCTHAT.
