Not sure if I understand it correctly, but anyway... The kernel is not being 
updated, but rather installed concurrently with other kernels. So you cannot 
create a delta rpm for it, since there is a completely new rpm coming with 
each kernel. If kernel was supposed to be *updated* then maybe you could 
create a delta, but if you want to *install* it (from scratch, as is done in 
Fedora), then delta will not help.

And if you want to have multiple kernels available simultaneously (in contrast 
to SuSE), you need to *install* each of them, not update from one to another.

As for the presto and delta rpms, it typically saves 60-90% of my bandwidth 
with each update, and works flawlessly. Developers did a fantastic job! :-)

Best, :-)
