David -

This is a topic I'm still trying to get straight. Are the following statements correct?

* both an in-process and an out-of-process server can be instantiated on a client machine from the object definitions (EXE or DLL) stored on another machine
* the in-process server class is created in the memory space of the application running on the client machine.
* the out-of-process server is created in the memory space of the server.
* if the server is across a WAN, communication between the UI and the in-process will be much faster than between the UI and an out-of-process server.

Thanks in advance!
