Is there anyway to generate a report that lists machines that have RPMs
that are not current compared to what is in the bundle/package mirror?

I know that in 6.6 it listed them in the individual inventories as having
an update available, but I don;t see it in 7 anywhere. In the SOX world we
need to prove that the servers are up to date and a comparison report
should be able to be reported on...all the info is there, but it seems that
there is no way to generate a report.
