nobody is just that "nobody" it is a user who 
doesn't exist and they are the lowest man on the 
chain of command.  Most damons will run as nobody 
for the porpose of *not* giving the application 
any access to any resources (none whatsoever). 
Simply do their own thing and not interfer with 
anyone elses stuff.
