How do I prevent others from writing applications that access my
remote objects? As it stands anyone can access my remote functions by
writing there own application. I want to restrict access so only my
applications can access the objects.

The built in security only seems to work on a user or computer basis
and does not prevent other applications running under the same user
account accessing the objects. As it is a commercial application I can
not start creating new user accounts on the customers PCs. I am using
IPC Channels so it is already restricted to an individual PC.
