Isn't pretty much everyone moving to custom web applications for internal services? I doubt that in those cases it matters much what platform you're on since it's probably running on Apache on a linux server anyway. I've seen this model even at tiny companies, and my impression is that it is also how the big ones do it. There are limitations, but the benefits are pretty substantial.
