This is a quite good project. However, I have a suggestion for improvement.
Is it possible to include a DNS server in a XAMPP, or to publish it as an add-on?
Lets observe using XAMPP on a home or small office network. The way it is now, all clients must enter IP addresses (which are hard to remember when there are more servers) in their browsers or administrator must update hosts file on each client computer. With DNS server being a part of XAMPP it would make maintaing small networks somewhat an easier task. Furthermore, it would enrich this whole project by making it a complete solution for web publishing (DNS+HTTP+PHP+MySQL+FTP+SSL+....).
