What is the best way to track work under an initiative?

[sohmc]

I'm trying to find a good way to track work for all work that's happening across all projects that are tied to an initiative.  Ideally, I'd like to look at this as a Kanban board.

Let's say I have a project where all initiatives are tracked called "Corporate Initiatives" and say we have the following issues:

• CORP-42: Get Green LEED Certification
• CORP-43: Implement Quantum States across all work sites
• CORP-44: Upgrade to Windows Bob

And say we have 50+ projects that tie to different teams.  What is the best way to build a view where we can see Epics/Stories/Tasks tied to each initiative and see them go left to right?
