Fedora.us sync with devel

[Ivan Gyurdiev <ivg2 cornell edu>]

Why is there no repository for the fedora.us packages that's in sync 
with fedora development? I've noticed fedora-devel packages tend to 
update in batches in order not to break dependencies. It becomes a pain 
to make fedora devel work with fedora.us packages against the last 
release. Isn't the idea to merge the two anyway? When will that happen?
