You know, I hadn't actually considered that! That certainly could solve quite a lot of the security problems, but as you say it adds a layer of complexity to an already complex method of using my computer. Excellent idea though :-)

If you think OS X offers better dictation/accessibility support than Ubuntu does you can also virtualize OS X on OS X using VMWare Fusion. I'm sure there are other ways of doing this but I know that VMWare Fusion supports this [1]. I don't believe that you will even have to pay for licensing OS X since it is already on an Apple manufactured hardware.

You are correct, the OS X EULA since 10.7 Lion has allowed two additional instances to be run within virtualization at no additional charge. Here is the EULA for 10.8, search for "virtual": http://www.apple.com/legal/sla/docs/OSX1082.pdf

("...you are granted a limited, non-transferable, non-exclusive license... (iii) to install, use and run up to two (2) additional copies or instances of the Apple Software within virtual operating system environments on each Mac Computer you own or control that is already running the Apple Software, for purposes of: (a) software development; (b) testing during software development; (c) using OS X Server; or (d) personal, non-commercial use...")

I use this exact method to get around VPN restrictions. Works great running a VM Windows 8 within another instance of Windows 8. On an SSD the VM seems to be as fast as the actual machine.

How does that get you around VPN restrictions? Do you then forward your traffic through some proxy?

I think the virtual machine is vpned and the external machine is not. Then you can get all the traffic you need passed through the inner vm while still getting outside traffic on your main.
