It is not easy (and may infact be impossible) do do this with FTP.  Some
ideas:

1. Seperate the stuff into anonymous FTP versus non-anonymous FTP. 
Local users will use non-anonymous FTP.

2. The seperation of global files versus local-only files should happen
as far up the FTP tree structure as possible.  Also, the splitting
should not exist in multiple locations.  I.e., you should not have
local-only content in one branch of the global tree.

It is much easier to do this HTTP.  The HTTP access control mechanism
using .htaccess is very sophisticated.  You can grant or deny access to
content based on IP address (range), username/password, cookie etc.
