In limited cases, it might be possible to implement this with the help of 
Loki's binary patch tools (or some other binarry diff utility) and present 
RPM. 

I mean, suppose you have a package, say kernel-2.4.10-2mdk. You make it 
provide the_kernel = 2.4.10-2mdk.

Then, when Kernel 2.4.11-1mdk is released, you create 
kernel_patch-2.4.10-2mdk-2.4.11-1.mdk, which requires 
kernel=kernel-2.4.10-2mdk, provides the_kernel = 2.4.11-1mdk,
and patches the files when installed. (Of course, uninstalling get kind of 
difficult <g>). 

IUn this way, it's possible to provide limited patch-update functionality, 
but it's hacky, and requires RPMs to be created separately for eahc upgrade 
path which may or may not be a big deal..
