I vaguely remember a post a while back (maybe a year ago) where they said they can't make a part of their remote technology open-source. Maybe things have changed, but I was quite sure it was something they were keeping close to them.

Also thanks for pointing out the certificate issue. I was actually leaving it that way on purpose, but I guess it can reflect poorly on my product, so I should just update the landing page with something non-descriptive.
