>Out of process EXE's can't have any UI elements.
Just to clarify... Out of process EXE's CAN have UI elements, but they of course run on the server that the EXE runs on, so that doesn't help with this scenario.
Example: Web Connection has an option to show a status screen on the server for each EXE running, with buttons to see its configuration, check hit logs, and shut it down.
