Protecting Windows

[Brian Astill]

Greetings, all.
Can anyone help with this issue?

Person with deteriorating vision has discovered Dragon 
Naturally Speaking which not only allows the construction of text 
from speech but can also speak from received text.  ie letter writing 
and email conversing etc become possible for the visually impaired.

All of which is wonderful except - you guessed it - the %$$#@*& 
program runs on Windows 2000/XP only.  Why would anyone in their  
right mind NOT port a program as sensible as this to a SECURE OS?

So .. what can be done?  Would a good firewall (FBSD?), then distro of 
choice (Ubuntu) and run 2000 in a virtual machine from Linux, protect 
our visually impaired operator from inadvertently triggering a 
virus/trojan/worm embedded in an innocent email or text-based 
web-page or VB-embedded-script in a MSOffice document?

What arrangement would you suggest to enclose Windows in a "safe" 
environment? 

Alternatively, anyone know of a "Dragon Naturally Speaking" port to 
*nix or an app that achieves the same effects in OOO and (say) 
Firefox?
