VMware
VMware continues to explain how the open source version differs from the commercial version in the FAQ:
Our goal is to work towards making the open source version as close to the commercial version as possible. However, we do currently make use of certain components licensed from third parties as well as components from other VMware products which are only available in binary form
Interesting move by VMware, as it really isn't that long ago that users were not even allowed to redistribute VMware tools pre-installed inside their virtual appliances. It will be very interesting to see what improvements the open source community will bring to the table as people start hacking the code.
Exciting, but I have one question: What happens if the OVMT over time ends up being a better product than the original VMware tools? Specifically, what happens with the Windows version of VMware tools if OVMT gets improvements released under the GPL that the Windows version would benefit from? VMware can't port the code back to the non-gpl version and only release it in a binary form now can they?
