Not me :-) An x86-64 host port would be very interesting because the 64
bit host MMU could be used to remap the whole emulated 4GB address space.
I think that there is also a lot of potential for a "code-copy" mode
converting x86-32 to x86-64 code (look at what I did for . Along with
the 4GB space remapping, it would give close to native performances
without requiring any potentially unsafe kernel module (unlike the
popular virtualizers).
