Demo mode OR under construction mode

Hi

I dont know if this has be done with codeigniter or not. But I am looking for a nice and decent way to achieve this.

What I am trying to do is, run my CI website on a public domain, and do my testing and stuff on it. I know you guys would be wondering why I am not doing this on my localhost ... thing is, I am trying to integerate DISQUS and some other online services which require a public URL, hence I need it as so.

So while I am testing and doing development under the hood, I dont want visitors to be able to see my website other than an Under Construction page or Coming Soon page.. etc .. you probably have the idea.

What I am looking for is something same as demo mode plugin used in Wordpress .. any ideas?
