To be blunt, that's still too much for me. I'm already unhappy about my ISP having my DNS history, I certainly don't want to offer it to a third part for a service that I could run without giving up that info.

I don't say that as a product criticism, I see why you can't do it another way and plenty of people won't mind. But if you're curious, that takes me out of the pool for this service. Shipping trusted hardware that could go behind a router is about all I'd be open to.
