1) rather than ratings between -10 and +10 why not just keep it minimal so: -1 (failed), 0 (resolved) or +1 (succeeded)
at least on the plus side, it would be nice to have a range (similar to the 5 star system).
Ideally, I'd like to see the AudenX.com website develop into a showcase of how such an open protocol can work, and of how easy to use it could be.
the problem as i see it is that this should really be integrated into the CLIENTS. so unless you plan on offering your own client, what you are currently suggesting sounds to me like a new proprietary protocol that you want the currently OPEN clients to adopt. i don't want to in any way discourage you from what you're doing, its just that i'm just starting to see the trends in bitcion and they all seem to move towards OPEN / DECENTRALIZED protocols.
i'm currently working on a fork of bitcoinjs, which comes with its own web-based client -- similar to blockchain.info's mywallet. i'd love the idea of integrating a blockchain wot into this client.
GPG is already too easy how much more easier do you want it?
i know you're not serious. you couldn't possibly be serious.
