Inkwire is one of my favorite projects. A dead simple way to remotely help someone out on their Android. It ties in a bunch of different technology stacks that I'd picked up over the years: video encoding, WebRTC, Chrome/Pepper, etc.
Inkwire works stupid well. But, it's not one of those things that I see really getting heavy usage. I could throw a price tag on it, and make a few hundred a month, but that honestly doesn't seem worth the time.
I've pushed Inkwire to the production/stable channel, and decided to make it completely free for non-commercial use. Though, I do reserve the right to pull it if server costs become unwieldy :)
Have at it.
