Running it in UML will probably give you the best bulletproofing options 
as a safe precaution. Plus you can just do a quick image restore if it 
does get broken.
I believe Jeff is looking at some technology in the near future that 
will let you watch what the UML is doing real time and save that info to 
disk for replay if you hit a bug, could be useful for what you want to 
do also.

Let my grandmother at the keyboard, she can break anything.
