OK, I guess I'll be the wet blanket that goes thud here, but I really don't see this being very useful. In fact, I see it encouraging bad practices. Maybe it's because I'm approaching this from the standpoint of a company that has more than a few users coming to the site, probably (hopefully?) has an existing release process in place and has multiple stages of their environment to go through (sandbox/dev/qa/staging/live). If this is how you slap lipstick on your pigsite, then you're probably building a site that very few people go to and you don't even have a local version of your site to test against first (because if you had a sandbox environment this tool is pretty much moot), in which case I can see the usefulness of this tool.
Not sure how I feel about the inclusion of the link/script tags in order to make this work but it all seems geared to someone who maybe has their own blog or very low-trafficked site and this would be their alternative to editing the files on the live server.
