I'm sorry.  I misunderstood what was written.  I was under the 
impression that to run Windows or unmodified operating systems quickly 
required a great deal of complexity on the order of vmware and that you 
could run Windows slower (under certain circumstances) with "simple" 
emulation features

I was under the impression that the performance degradation for qemu was 
on the order of 3x native which would be a bit problematic for speech 
recognition.  Is this impression wrong as well?

tell me about it.  I am heavily involved in the Open Source Speech 
Recognition Initiative (www.ossri.org) and just trying to figure out 
what's necessary to make NaturallySpeaking work on wine is a handful 
because we need to make it tremendous number of assumptions about 
NaturallySpeaking.  Scansoft, the current owner of the desktop speech 
recognition monopoly, views customers as a hostile necessity and doesn't 
provide any support to anybody for any reason unless you show up with a 
big fat checkbook.
The open source speech recognition engines are "cute research projects". 
 To get something useful will take approximately five to eight years of 
work and $40 million.  in other words, we're going to need some major 
grants.
as for wine and NaturallySpeaking, we can't get past install.  Again we 
are going to hunt for grants sometime after the first of the year to pay 
for the evaluation and development.  It wouldn't be entirely fair to go 
to the wine community without some compensation for their efforts.
