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
Might be the blocker criterion, however.

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.)
Creating a tmp dir that contains symlinks to the repos would work?
Another hurdle is that the rpmfusion-free repo (= releases -> Everything)
is not maintained within the pushscript configuration file. Only
updates and updates-testing are. Example:
'9' is the dist id for the RPMFusion F9 updates
'testing/9' is the id for the corresponding test updates
The absolute/relative path to the releases/9/Everything repo tree would
need to be added via new config values. Not a big problem, though.

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.
I've set up some files to test presto-utils here.
One thing that doesn't want to work is 'createprestorepo -m <repo
dir>'.
It says "Delta directory must exist." which is nothing I understand
without examining the source code.
