Very Computer

I have an encrypted executable file which I wish to decrypt and execute
directly within a program (e.g., exec) without creating an intermediate
output file from the decrypted output (i.e., the original executable file).
In other words, I want to execute the output from the crypt command which
has decrypted the file as if I were running the original program.
I tried to set up a named pipe, thinking that somehow I could execute the
stuff if the pipe was used in an exec call, but, of course, this didn't work.
I have the feeling that either this is totally impossible/unreasonable or
so trivial that I'm totally overlooking somwthing.  Any ideas???

Thanks,

Is the executable a shell script?
If so, try crypt < infile | sh
If not, I think your only choice is to get some sort of
"virtual-file-system" software (heard something about it in
comp.os.linux.announce), and write the temp file to memory, and execute it
from there.
