Give them a DLL that just tosses an RPC call to a secured server that you
manage.

In general, if it's (even potentially) in their address space, they can misuse
it. So the only real solution making sure that your Secret Sauce code is on
some other system where they can't find out it's just Miracle Whip and a shot
of jalepenos....

Another, even better, idea is to give them a click-through EULA that contains
a line of the form "misusing or reverse-engineerng our usage of jalepenos will
result in a $MOBY surcharge and/or other legal action...."
