Personally, (for what its worth) I also felt that this idea was more-similar to RealityKeys than you've described, and even though this was never explained to me, assumed that RealityKeys would be some kind of "gear" in a bigger mechanism (like a multisig 3 of 5). As I mentioned on twitter, trusting >1 oracles isn't as magically decentralized as one might hope, as someone can generate a number of fake identities and wait for an opportunity to strike.

One thing I like about RealityKeys (which makes it, currently, my favorite trusted-feed solution) is how their business model cleverly plays with the economics of trust (requesting a key is free [only efficient if this part is automated], but they 'charge' for the truth, aka independent verification, so the truth is what they need to focus on, but it is off-path so would never actually need to be used [unless project grows very large]). I haven't looked into it, but I'm skeptical that people will want to become a Orisi oracle and supply data. How much can they reasonably expect to be paid for this tedium?

I really like the idea of using Bitmessage to trigger oracles and am really excited for all of the new attention that this space is getting. I still think that I have the only truly trustless and decentralized solution, but that's far from saying that I believe my idea is going to be useful, let alone the most popular.
