Whichever machine builds the deltarpms needs loads of RAM (mainly for
the really big rpms).  Specifically, you need (uncompressed_size_of_rpm
* 3).

Other than that, not much

I know deltarpm is available for EL-5, and if presto-utils isn't, I'll
push it out.

Yes, though if you're doing rpmfusion-free and rpmfusion-updates-free,
ATM that path needs to be a parent directory of both.  In the test
repositories, I kludge it by making a rpmfusion+updates-free that
contains symlinks to rpmfusion-free and rpmfusion-updates-free. (If
that's not clear, check out the directory layout in
http://lesloueizeh.com/f9/i386 and you should see what I mean.)

Yes

Yes, that looks *way* simpler than the proposed method in Fedora.  I've
got some time tomorrow; I'll see what I can come up with.
