Have you heard of Intellectual Property Agreement? This is a job for
lawyer not security. I don't know why you think VNC is secure.
Couldn't he use screen capture program and take a snapshot of his VNC
session every 2 second while he is editing files. How is this
different than copying file? With patience, it can be done (just
scoll down the file slowly).

If it is that important to you, I would consult the legal department
of your company. How effective would he be, if he can never see the
whole file and he needs your permission to open any file? Is
babysitting part of your job description? This is one of the reason
to have a legal department.

Think about this situation. With screen logging turned on during a
terminal session. A user just type:
cat */*/*/*/*/*
He/she would be able to re-assemable any files on your file system.
