Some comments:

1) There's a great deal of related and prior work in this area.
Take a look, for instance, at Janus, consh, MapBox, SubDomain, Ostia, ...
http://www.cs.berkeley.edu/~daw/janus/
2) There are some real problems with using system call interception
for this purpose.  There are TOCTTOU races, synchronization issues, ...
http://www.stanford.edu/~talg/papers/pubs.html
3) Have you looked at the LSM (Linux Security Modules) project?
It looks to me like this is what you want to be using, and it avoids
the problems with system call interposition.
