			System administration is generally local -- only because somebody has to locally install the things that let people work remotely. 
 
Nowadays "integrated lights out" is all the rage -- things that let you *really* run a computer from anywhere on the Internet.  At my previous job, we became remote sysadmins as much as possible, but there's a limit where somebody actually has to be on site -- to change out disk drives, diagnose hardware problems, that sort of thing.
