It's come along way.
I was guinea pig for it when it first came out. I had the new Focus Hatchback, it was horrible then but the revisions now make it much better.
As for hacking, yes, pain in the ass. I was able to crack it enough that I could redesign the artwork (they are flash files) and make my own custom UI. The problem I had was I couldn't break it enough to force a maintenance mode to upload the revisions. Ford was pretty smart and encrypted it enough that I didn't have time to figure it out. I pretty much gave up on it a longtime ago and the only thing that came out of it was an awesomely designed interface.
If I had access to Fords tool that refreshes the entire module, I could probably do something. It's not hard, the damn thing runs on a Microsoft operating system.
