Another good thing to do before diving to far into the mockup is to take
a screenshot of various package web systems and in the gimp or in a
similar way, point out the sections which are important so we can assign
labels. I would suggest setting up a wiki page off of the MyFedora wiki
page (http://fedoraproject.org/wiki/MyFedora) for package info.  Once we
have a list of labels you can then do the mockup using the labels as
placeholders.  We can drill down this way to finally get a list of data
you want to grab.  I can then fill in the backend from there.

BTW here is the style sheet I am using (it is not complete yet):

https://fedorahosted.org/myfedora/browser/myfedora/static/css/myfedora-style.css

and the genshi template gives you an idea of the structure we use:

https://fedorahosted.org/myfedora/browser/myfedora/templates/packages/master.html
https://fedorahosted.org/myfedora/browser/myfedora/templates/packages/builds.html

The template language may look a bit weird at first but you don't have
to worry about loops and such, just how the css elements are used.
