That would be interesting. Qemu can't do that yet (it shares hardware via
the help of the host OS, of course, but not direct access).
If you had qemu running multiple OSes, and all of them could access the same
hardware "virtually directly", that would be simply amazing. Not quite sure
how one could go about doing this though..

No, it currently only works with PCI. ISA, AGP, USB, and traditional hardware
can't be accessed directly yet (tho it is theoreticly possible).

Infinite complexity begets infinite beauty.
Infinite precision begets infinite perfection.
