Indeed. Use Authorization Services to query the system about whether  
you currently have the rights to perform a particular action, and if  
you don't to request the user to authorise you to do so (e.g. by  
entering the login and password of an administrator user).

And he can of course also look at the source code of existing VNC  
servers, e.g. http://sourceforge.net/projects/osxvnc/

But since it's such low level stuff, it's likely to require  
modifications for different OS versions and using an existing (and  
nowadays system-provided) protocol is indeed probably the best way to  
go.
