Syncing development environment between OSX and Windows

I currently have a portable XAMPP server on a USB flash drive so I can develop on either my desktop or my laptop.

However, recently I bought a m开发者_运维问答ac laptop, but I'm still using Windows on the desktop. Now I can't use the USB flash drive trick to code anywhere.

What method would you suggest to have two local development environments (on laptop and desktop) that are both synced (even databases, server settings..etc)?

I'd like to be able to work locally not remotely, since many times I have to work in a place where I don't have an internet connection.

Your input is much appreciated
