I tried looking for source but was unable, vmware is a closed source as far as i can tell(please correct me if im wrong, as i like to get hold of the source) when i was looking for it online you have to download the binarys, and you have to email in for a serial number to use it, they also have higher up pay-for versions, with more features
It is closed-source, however source to the kernel modules is distributed with the binaries, even if not with a free licence. I imagine that this would help with reverse engineering the driver, although I'm not sure whether the use of this as an aid to reverse-engineering the driver would be allowable under project policies. -- Lachlan
