[vbox-dev] utlizing the nvidia card of the host machine in the vm

[Mario Lobo]

Klaus;

Hijacking the topic a bit, what would be required (technically and
"licensingly") to implement these basic pci passthrough
functionalities on the ose source (freeBSD in particular), specially
for using it on sound cards?

Thanks, 

P.S. - Sorry for top-posting but it seems to be the trend on this list.
