As of Wednesday 13th June 2012 it's possible to browse the files at http://downloads.jboss.org/<project> using a new 'Directory Listing' paragraph in Magnolia. This saves you the work of manually creating download tables and allows additional information about each directory, and/or a link to the latest download, to be permanently displayed above the table along with an RSS feed of the files available in each directory. An example of how this looks and works can be found on the following help page along with instructions on how to configure it:

This feature was made possible by the integration of Magnolia and ModeShape in collaboration with the Magnolia Community.

Enjoy!
