Check out this article which has some nice details on how PolicyKit is

"We’re used to think of system-enforced access policies as crude and 
coarse-grained, such as the setuid permission bit that lets a user 
execute a program as the file’s owner. Fine-grained access has to be 
enforced by individual applications, a laborious coding process that is 
weakened by not being able to take advantage of underlying operation 
system security. PolicyKit, developed by Red Hat and included in Fedora 
8, ameliorates this unsatisfactory situation."
