I think it would be really interesting to do both a video series and a running blog.
I think if the videos were a good blend of actual map work (sped up with voice overlay) and interviews, people would really like it.
If the interviewees have webcams or camera, they could film responses; if not, you could post the interviews on the blog, along with other considerations that you couldn't fit into the videos.
In addition, the community could get a big awareness campaign going, and try to hype up the eventual release so as many people put the map up on servers as possible.
I'm sure people would be willing to fund a project like this, especially if you made a couple of example videos to demonstrate the quality of the production.
