Hi, I am making them! I created reportsfortrello.com. I am adding new stuff all the time. Let me know what you need and I'll add it if I can.
Yeah, drives me nuts there's zero reporting/analytics. Considering leaving Trello altogether because of this.
Jira has a kanban feature now (Greenhopper, I think?). I have seriously considered it, although I am fearful of the ability for PMs and clients to use Jira's bazillion other features to make my workflow process hell. I do enjoy Trello's forced fluidity, and cannot wait to port my last few clients off redmine (love the project, kanban fits my flow 1000x better).
GreenHopper has just been renamed to JIRA Agile recently.
