Access a Vagrant virtual host with xip.io
This tip is for people that would access a Vagrant dev website from another VM (let's say to test another version of Internet Explorer via e.g. https://github.com/xdissent/ievms) or via another device than the host environment (smartphone, tablet, ...).
Vagrant allows you to quickly deploy dev environments on a Virtualbox VM.
xip.io will let you access your dev website from other devices (already tried to patch /etc/hosts on an iPad?)
