They would probably publicly denounce it and implement it in private if they even thought it was worthy. That's how it works. Maybe I should take a longer break from my current project and be the first to get wifi then bluetooth working on it.
I also have other ideas about the effort. Sierra Wireless is Canadian and patents might be limited for their "IP" in other countries. It's already been posted many times online. I can respect the Clean Room process but the competition has announced some insanely capable hardware that is coming soon.
