The RTD server is just a COM object that implements the IRtdServer interface. Excel has added an IRTDUpdateEvent interface. The RTD server and Excel communicate with each other by calling into these interfaces. This is done through COM when the RTD server is running on the local computer, and it is done through DCOM when the RTD server is on a separate computer.
