[PLUG] Self-hosted "card wall" tool?

[JP Vossen <jp@jpsdomain.org>]

I'm looking for a "card wall" or Kanban tool that I can host internally. 
 Trello.com would work great, but since that is cloud-based all the 
security people's heads exploded (including mine, sort-of).

Linux (ideally CentOS) and free of cost is required (don't ask), F/OSS 
preferred.  Any clues?

Thanks,
JP

"Microsoft Tax" = the additional hardware & yearly fees for the add-on
software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
