He needs to write a new front end.  The front end should have the script 
compiled into it, then after initializing R,
it should parse and execute the script.

The executable won't be self-contained.  Normally R is compiled into 
several dynamic libraries (.dlls on Windows); it may be possible to 
compile it statically.  However, R relies on its own library directory 
containing installed versions of packages.  As far as I know there is no 
way to avoid using that.

By the way, your guy shouldn't expect any support on doing this in the 
R-help list; it's a topic for the R-devel list.  And he may not get much 
sympathy there:  R is an open source project, and developing ways to 
hide code is not something that interests most of us.
