Obviously I agree with you on that.

Indeed that would be interesting to see.  Right now on my Windows 7
machine I can see that Firefox is running with virualization disabled,
just like my manifest-hacked Emacs.  So obviously Mozilla's done
something.  Ah, wait a sec - let's look at their manifest - it's
pretty similar to the one I inserted into Emacs, actually.

Of course, it's quite possible that people who see VirtualStore as a
problem are a small minority among Vista and W7 users: maybe most
people still run as admin.
