A lot of people have been taking potshots at me for having asked the original
question, so let me clarify. 

I know how to protect my files from being `rwx' by others.  That is not the
purpose I had in mind. I was just curious to find out if such a monitoring 
program is possible on Unix machines.  There can be non-paranoid uses for
this, such as keeping statistics on the usage of a particular program in
my home directory by others, for example.  

I gather that it's not possible to do this, short of overhauling the 
kernel.  Thank you.  We now return you to your scheduled programming.
