Two browser functions are among the very first that newbies learn -- and that "non-web-tech" people seem to rely on in the extreme. They are"click on the X to close" and "back button". It's my experience that messing with those functions severely limits the audience, and in this case I know the audience is only minimally tech-savvy.
It's just a fact of life that I had to accommodate with this project. But the embedded server is a great solution for this case. And though I am far from being Mr. Server Admin, I had no problems at all -- mostly because the default install pretty much handled everything I needed.
