But once the file data is in a program's buffer then there are no
permissions inherited from the file for that memory. Even if you
design such an system, its trivial to write 2 separate process, first
process will read file data and pass it to other process by using
COM/DCOM or just TCP/IP sockets and the second process will write the
data in a new file.
