They're open sourcing the JavaScript engine, not the browser. A port to OSX would mean you can run there server side programs before deploying them to Windows servers. I believe there are more Linux servers out there. Still a port to OSX would be useful because there are many developers with Macs that deploy to Linux.

I don't see how it'd help deploying server-side programs. Maybe that makes sense with IoT. And as a Node alternative/enhancement.

BUT, once you have the JS engine over, I could see them porting over the rest. But anyways, you could still run headless browser (or just Chakra) and run tests against it.
