LAMP on Virtual Machine, files and development environment in the host (Windows)

I know that Quickserver it's meant to have the dev environment also in the Virtual Machine, but I'm finding more suitable for my case to have the dev environment on Windows.

So I still use LAMP stack, Drush, Aegir, and all that *nix tools that come already with Quickserver but the files and development environment is Windows 7.

Other alternative I was considering is to have a separate dev machine on your LAN instead of a Virtual Machine and share files over the network.
But if you have a separate dev server file transfers/search are quite slow, so probably to have a Virtual Machine in a powerful host PC I'm finding it's the best solution (for personal use. Work teams is different)

To have this setup I was telling initially, basiclly you need 2 extra steps configuring your VM:

1. To have access to the your Virtual Machine Network (from your Windows Machine) it's a no-brain setup: In the VM Settings, enable Bridge Networking. Start the VM machine, connect, guess the IP of your VM (or add it manually) and add it to /system32/etc/hosts in Windows.

   In my case this line:
   192.168.100.140 dev

   Then from Ubuntu you can access with http://localhost and from Windows with http://dev

2. Then for share the folders in the VM settings-> Shared folders, select the folder and give exactly the name "shared" so it works out-of-the-box, and the shortcut in the Ubuntu desktop works.

To have dev files in my hard disk instead of VM hard disk, gives me some tranquility. What if VM get corrupted and I can't open the VM?
(Note that can be seen as an adventage http://crackingdrupal.com/blog/greggles/easier-and-safer-drupal-developm... )

All this is quite theorical still in my head, and let's see what kind of issues I have with file permissions, git, debugging, and other stuff that will come for sure.

I wonder what kind of experiences do you have with this setup? And what flaws do you see?
