Re: Or... no snooping at all
When I've needed to use Photoshop or play old Windows games, I've ran a VM with Windows 7 inside it. Gave it enough RAM and CPU, and it's ran like a charm. I also introduced this to my team (consisting of me and 2 others) and it ran fine. Windows never needed to access the internet, so we didn't give it internet access. So the fact it was cut off and only accessed a shared folder on our hard drives (so we could swap files from Linux to Windows, handy for keeping your collection of ISO's off of the VM) it wasn't a security risk really.
I approve of this method, basically.
