I actually don't think introducing IOTHREAD made Windows a second class=20
citizen, since it was left as a non-default choice for years.  People=20
care about IOTHREAD now only because (after years) there is serious=20
thought about making it the default.

I'm sure that if you add such a killer feature that is TCG-only, KVM=20
people will try to support it in a shorter timeframe.
