koji vs. dropbox

[Polychronis Ypodimatopoulos]

This is probably meant for the release team.
Is the dropbox mechanism for updating rpms in joyride still working?

According to http://wiki.laptop.org/go/Build_system the dropbox should 
work but newer RPMs of cerebro don't get pulled into joyride. Rumors 
have it that this mechanism no longer works and koji must be used 
instead. Are there newer instructions on the wiki anywhere?
