When your trying to implement a new feature(say a module or theme) in your local machine for a website, first thing you have to test is the compatability in all browsers. If you want to test your feature in multiple machines, its not always easy to download and setup on each machine. In my case, I am using Ubuntu and I have to always test compatability of a site in IE browsers which cannot be installed in ubuntu. So what I did here is created a virtual host for my site in my local machine and using my ip address I created a virtual host in other machines so that I could easily access all my sites in my local machine from diffrent machines.
