We use Signavio for workflow and process diagramming. As part of their platform, they offer the ability to grab some HTML for a diagram that's been created and drop it into a Wiki, thereby offering a "live" include of a diagram image that will update whenever changes are made to the source doc. This would be very valuable (and slick) for our purposes.

We've changed your idea slightly to reflect an idea around embedding iframes
