If name of file mapping is known for all processs 
it is impossible to do restriction for write (just as 
you said in your first letter).

If name of file mapping is unknown it is possible to 
restrict access for writing in shared memory. For this 
DuplicateHandle is needed (as I write in my first letter).
The question WHO will call DuplicateHandle is not important 
because in both cases IPC needed. Even calling from source 
process is preferable because this process gives service for 
another processes.

If to return to initial question it is not absolutely 
clear what case he means but seems to be yours.

Vladimir.
