Re: [Qemu-devel] Code Copy / New Linux boot code

Jamie, your rootless windows concept, in conjunction with QEMU's
emerging ability to provide VMware-like virtualization in a GPL package,
could be an excellent way to make existing Windows speech recognition
software seamlessly usable on the linux desktop. If it's not too much
trouble, please keep me apprised of your progress in this area!

Best regards,
