How exactly would rpm know if an updated package is available somewhere 
on the net or otherwise? You need plenty of other infrastructure for that, 
for example see what yum, smart and apt-rpm do. Apt-rpm is in C++ while 
the other two are in python so it might be closest to you, just beware -
apt-rpm code is not exactly easy afternoon passtime reading :)
